WHY TIERS?

Rank lists and cheatsheets can be deceiving when they're presented without commentary. Our rankings have been vastly improved by adding staffer comments, but it can be hard to see the all-important context in the consensus rankings and sheets. It's critical to know where a significant drop-off in fantasy value occurs. A simple rank list can't tell you if the DL4 is closer in value to the DL10 than the DL3. A cheatsheet can't tell you if the ranker feels the LB10 is a boom-bust play with LB2 upside and LB40 downside while the LB11 has a much narrower range of expectation.

That's where tiers are helpful.

Using tiers allows you to lump and split players in context. Using tiers can help keep you on the right side of draft runs. Seeing that you have five linebackers of equal value left on your board might prompt you to take a player at another position. Noting that there's only one wide receiver left before a major drop in value will show you when you must draft a position sooner than expected. A tiered draft board keeps you from making panicked decisions while on the clock.

HOW TO USE THE TIERS

Note 1: These tiers are based on 2016 expectation in a balanced IDP scoring system. I stopped producing dynasty rankings years ago when it became clear I weighted the current season significantly more than future seasons. In deeper dynasty leagues, I'll save a roster slot for a strong developmental prospect but otherwise still use these tiers as my primary roster philosophy. A separate dynasty stash tier is included at the end of each positional article.

Note 2: I'm basing positional classifications on the MFL database (which syncs to the Rotoworld depth charts). Early in the offseason, I'll deviate from the Rotoworld depth chart when I'm reasonably certain a positional change is coming that Rotoworld will reflect later in the offseason.

Note 3: I'll add a ^^^ for those players making a move up in my tiers and vvv for those players who have dropped since the previous tier release. For reference, you'll be able to see the earlier versions of these tier articles within the IDP article list, but the trend column should help you see where player movement is happening within the tiers at a quick glance. I'll also be including an ADP column after training camp begins. The ADP number will be an average of our FBG rankings, the FantasyPros Consensus Rankings, and ADP data from drafts at MFL.

Finally, the date on this article represents the last time the tiers were updated. Each update will be published as a stand-alone article. Make sure you are viewing the most recent tier article by checking the complete IDP article list here.

That's a long, but necessary, introduction to the important stuff. Thanks for bearing with me.

STRATEGY THOUGHTS

Ten years ago, the defensive back position used to be one of my favorite areas to rank. Offenses were straightforward, base defenses were stable and teams rarely platooned players. If you had a working knowledge of the coverages a team preferred to run and the skill sets of the secondary, you could make smart, consistent bets on which players were likely to see the most statistical opportunity.

Unfortunately, the league isn't simple anymore.

Many more defensive backs average statistically relevant snaps per game than defensive linemen and linebackers.

Not all of those snaps are created equally. Game situation, down and distance, personnel and surrounding cast have much more to do with the fantasy upside of any given snap than ever before. Free safeties moving to the slot, strong safeties moving to linebacker and non-starters moving into a key tackling role on subpackage downs are becoming more and more common. It's become very difficult to project yearly and weekly tackle numbers for defensive backs.

And that's changed my roster philosophy for defensive backs over the past 3-5 seasons. I now believe that there are two main tiers for DB-inclusive leagues. The first tier includes the players I believe have Elite DB1 potential -- 80+ solo tackles or 60+ solos with elite peripheral coverage stat (FF/INT/PD) upside. The second tier includes everyone else.

It's also important to have a short memory. If an "Elite DB" isn't performing as such, move on. It's okay for your defensive back roster spots to remain fluid all season long.

I'll still be lumping and splitting players into tiers in this feature. But realize that every single defensive back that could see 40 or more snaps in a given week belongs somewhere in the matchup cloud. You're probably thinking, "Come on, Bramel. That's almost 200 players." Yup. Hopefully, you've grown accustomed to that over the past 2-3 seasons.

Scouting IDPs is as much about scouting opportunity as talent. The paradigm has changed. We've adapted to front seven rotations and nickel linebacker specialists in recent seasons. It's time to do the same with the defensive backs.

HIGH FLOOR ELITE SAFETIES | DB1

Unexpectedly elite fantasy options present themselves in the early weeks every year. If you're aggressive on the waiver wire in the first month, you can often stumble onto a player you hoped to stream who becomes too valuable to dump back on the free agent list. Still, if these elite options remain available after the best offensive depth and highest DE/LB upside is gone, snap them up. They are the best combination of upside and floor on the board this season.

It wasn't quite as impressive as a typical J.J. Watt season, but Reshad Jones was far and away the second most valuable IDP last year. He averaged over three points per game more than any other defender -- including Deone Bucannon. The addition of Kiko Alonso will make it very difficult for Jones to put another 107 solo (136 combined) tackle season, however.

HIGH VARIANCE SAFETIES | WEEKLY DB1 UPSIDE

I like this group this year better than most. Ordinarily, I reserve this tier for players w/ DB1 upside, but a DB3 or worse floor. This year, I think the weekly floor is closer to the DB2 range. That means the safety group is deeper than usual.

I think it's likely 2-3 players from this tier will move up as their situation solidifies in camp. I think Kenny Vaccaro is close already, as I'm not particularly high on James Laurinaitis at middle linebacker. Ibraheim Campbell is set up for a monster season. Every name on this list has 80 solo tackle potential.

MONITOR CLOSELY

These players are either moving into one of the top two tiers in the coming weeks or moving out of the tiers altogether. I really like the upside of the top three players -- Calvin Pryor, Keanu Neal, and Shawn Williams -- and would absolutely roster them today over the "streaming" options below.

BEST EARLY SEASON STREAMING SAFETIES | WEEKLY DB2 UPSIDE

Conversely, I'm not as excited about this group as the group above. These are the players I feel are mostly likely to surprise as stick as more than bye week replacements on your roster. This list is short and just not inspiring. You should be adding them to your roster before the season starts in only the deepest leagues.

DYNASTY STASH

Recommended for deeper dynasty rosters only, this group isn't likely to impact your 2016 fantasy roster without an injury or unexpected depth chart surprise.

CORNERBACK TIERS -- fuhgetaboutit

Historically, you could do well at cornerback by grabbing the most physical players or trolling for Tampa-2 starters. That's not the case any longer. The days of Charles Tillman and Ronde Barber are long gone. The reign of Antoine Winfield and Richard Marshall are wistful memories of yesteryear.

Today, I'm no longer certain it's worth spending much time on cornerbacks at all.

Here's what I used to profile and favor:

1. A physical corner who will shed blocks and defend the run.
2. A confident corner with good ball skills.
3. A versatile corner who plays outside, then slides into the slot in subpackages.
4. A decent corner playing opposite a stud cover corner.
5. A corner who plays more zone coverage than man coverage.
6. A corner for a team likely to see above-average passing attempts.
7. A corner playing for a team likely to see high tackle opportunity with weak front seven tacklers.

The more criteria a player fit, the more attractive he was to me. You could be reasonably certain a player who fit many of these categories would have a chance at 65 solos and 10+ passes defensed. Those players still exist, but their statistical upside has cratered.

There have been five cornerbacks to top 65 solos in the past three seasons. Combined. And it's not a who's who of expected talent. Last year, Antwon Blake. In 2014, Jason McCourty and Johnathan Joseph. In 2013, Prince Amukamara and Josh Wilson. Twenty total corners over the past three years topped 60 solos.

Contrast those numbers with 2012 -- six corners with 70 or more solos and 13 with 60 or more solos. In 2011, there were two corners with 80+ solos and ten with more than 60.

It's a horrible statistical trend. And it's not a fluke.

For the past three seasons, you've read a different version of the same introduction above. More and more defensive backs are playing significant snaps as offenses spread their personnel across the field. The slot cornerback should be considered a "starting" defensive player. Dime packages have replaced nickel defenses as the standard passing down subpackage. When I first started tracking tackle opportunity and nickel data a decade ago, teams passed more than they ran about 45% of the time. It's now pushing 60-70%, with defenses playing subpackage defenses 80% of the time or more in some games.

Last year, my final cornerback tier article highlighted ZERO "Cornerbacks w/ Every Week DB1 Value." I just didn't lead in with an extended rant like this year. I listed 20 players I thought had a projectable floor. The vast majority of them didn't reach that marginal 55 solo plateau.

This year, I believe you should forget about the position altogether in your drafts. Don't draft a single cornerback. Use your final picks on linebacker and defensive end upside shots. Stream your corners during the season based on matchup. Roster and start players against bad quarterbacks who will have to throw the ball often. Re-evaluate every week. Should you stumble onto a player who resembles Charles Tillman or Antoine Winfield and puts up multiple consistent weeks in a row, stick with him. Otherwise, move on.

If you must draft a corner, look at players who primarily draw slot duty or who sometimes see snaps at safety. Antrel Rolle and Tyrann Mathieu would have fit this mold in the past. Sometimes, you were lucky enough to see them listed at cornerback. For now, I'm not certain I see anyone I'd feel comfortable enough to push. Maybe Jalen Ramsey or another hybrid with size like Damarious Randall who look to see most of their snaps at corner will fit that mold by the end of training camp.

I don't think cornerbacks are the IDP equivalent of kickers yet. But until the trend settles or we find new ways to value the best corners, you should consider a similar roster strategy.
