Well, I'm sure Wade was smart enough to know the Ravens were gonna run the ball and told his defense to focus on stopping the run.
They just completely blew it on consecutive drives. Ultimately, he'll have to take responsibility...head coach/defensive play caller, whatever...but the problem isn't actually him.
He's not the best defensive mind in football, but he's well above average. This unit just isn't that good...and that should've been established back when Parcells was still the coach. For whatever reason, Parcells chose a bunch of penalty prone players (on both sides of the ball) and there's just something wrong with the very foundation of the team.
