Aaron Donald, Defensive Tackle.
Despite being crowned Defensive Player of the Year for two consecutive seasons, undoubtedly the league's top defender, once overshadowing Watt's brilliance.
However, Donald remains clear-headed.
Watt won the Defensive Player of the Year honor three times in four seasons. His absolute dominance on the field made him a true icon of the league.
Yet still, it has been insufficient to place Watt in the discussion for regular-season MVP. Why?
The reason lies in the defensive ends/defensive tackles. While they can terrify quarterbacks and running backs, contribute twenty sacks in a single season, and turn football's power and collisions into an art form, they still cannot single-handedly determine the outcome of a game.
In the years Watt was crowned Defensive Player of the Year three times in four seasons, the Houston Texans failed to advance to the American League finals even once.
