Bosa's sack numbers have taken a nosedive since a midseason stretch of show-stealing dominance, but anyone who watched him crash the pocket on Drew Brees last week can tell you he's still a relentless force to be reckoned with every single snap. Tied with his brother Joey for second-most tackles for loss (15) in the NFL, Nick may no longer be among the favorites for Defensive Player of the Year. Make no mistake, though: He's running away with the rookie award. Allen's numbers have seen a similar second-half downturn on a face-planting Jaguars defense, but he still stands out for his rare blend of size, physicality and athleticism. There simply aren't many edge rushers alive capable of matching the Week 13 two-play sequence versus the Buccaneers in which Allen stalked Dare Ogunbowale from behind on a third-down reception and then corralled a scrambling Jameis Winston on fourth down for the drive-ending sack.
