Aaron Donald

Donald is likely the most feared defender in the NFL, though as a defensive tackle he has a more difficult path to IDP production than the typical defensive end. It's a testament to his inimitable talent that he places this high anyway, and it was only two years ago that he totaled 59 tackles and 20.5 sacks. It would be particularly good for Donald's IDP purposes if the Rams offense could bounce back to its 2018 level, but if it can't then he might not have quite as many pass-rushing opportunities as he did in his 20-sack season. Still, Donald is a lock for 900 or more snaps if he stays healthy, meaning he could offset any decline in sacks with an uptick of tackle production in run defense if teams throw less against the Rams.

Donald is pretty much beyond words. The glory days of pass-rushing defensive tackles have been gone for about 20 years now, and even in those days Warren Sapp and John Randle still never approached 20 sacks, which Donald managed to do on 916 snaps last year. It seems like an unsustainable sack rate, but much of what Donald does is supposed to be impossible, and yearly improvement has been a consistent theme with him. Expect some regression, but it's probably best to give Donald the benefit of the doubt until his production more obviously stabilizes.

If IDP utility perfectly correlated to real-life value, Donald might have been top-ranked among defenders generally, let alone linemen. Donald is a cannonball on the interior, blasting out of his stance at a velocity blockers can't prepare for and at a center of gravity they can't reach. With Ndamukong Suh around, offenses are left with a cruel lose-lose situation – offensive game plans would mean to double-team players like Donald and Suh on nearly every play, but there just isn't a reliable way to do that now. With 11 sacks on just 790 snaps last year, Donald could go wild in 2018.

Donald is expected to play nose tackle in Wade Phillips' new 3-4 defense this year, but that's not a concern, as Donald is a unique talent whose skill set should translate to standout production almost anywhere in the front seven. Moreover, Phillips coaches a one-gap scheme that will give Donald the green light for shooting gaps like he always has. If anything, Phillips should be expected to bring out the most in Donald, who's averaged 55 tackles and 9.5 sacks in his already remarkable three-year career. It helps that all of his NFC West opponents ranked top eight for sacks allowed last year.

For Donald to affect games the way he does as an undersized defensive tackle is remarkable, and he's definitely one of this generation's most uniquely great players. Listed at just 6-foot-1, 285 pounds but with sub-4.7 speed, Donald already has 19 sacks and 38 tackles for loss to his credit in 32 career games, so it's clear that double-teams just don't matter much to him. Not much should change in 2016, but things could actually get a bit better if Robert Quinn returns to full form. Running away from Quinn and running into Donald may be loosely synonymous.

Donald became an instant star after entering the starting lineup Week 6, earning Defensive Rookie of the Years honors as one of the league's most explosive linemen. A consistent tackler, Donald's pass rush improved late in the year with six sacks in the last seven games. His nine sacks were the most by a rookie in three years and second among defensive tackles last season. He also had 18 tackles for loss (2nd among DT, 4th among DL). Those numbers could take a jump this year with more snaps — he should see at least 800 this season after playing only 705 snaps last year.

Although Michael Brockers and Kendall Langford are the incumbent starters, Donald is going to see plenty of game time after being drafted 13th. Donald was a menace to offenses in college and with so much defensive line talent in St. Louis, he doesn't have the immense pressure of starting right off the bat.
