When the Bears passed on Carter, I was hoping that Poles had found a hidden gem with Dexter. I watched his reps closely in the Colts game and saw little to supply me that hope.
He shows no ability to power rush, and the opposing OL have little trouble pushing him backwards or to the side forcing him out of the play. What's worse, he doesn't show any aggressiveness; he has no motor or energy. He's slow to pick himself off the ground, as if he's tired, and he doesn't pursue the play until the whistle blows. I saw a few plays where if he had continued to pursue, he would have been a factor in the current snap.
When you watch Pickens, it's not hard to see an NFL player. Dexter not so much. I believe Pickens will end up being the better player. It's not too hard to envision Dexter being a bust.
Right now my hope is that I'm wrong and Dexter eventually "gets it".
