Analysis:

Despite those nagging tears, some of which occurred early in the season, and a broken left hand, Watt didn't miss a game and recorded 17.5 sacks in 2015. He earned Defensive Player of the Year honors for the third time in four seasons. Watt underwent surgery in January for what Houston head coach Bill O'Brien called at the time "a significant groin injury" and was cleared for offseason workouts in late February.
