Pratt was successful when he had good DT's in front of him who could slow down, redirect or trip up a RB. If a RB came straight at him full speed through an open hole, good luck.
DJ Reader helped the Bengals LB's so much. Pratt has gotten help all season from DeForest Bruckner (until he got hurt) and one of the most underrated DT's in the league Grover Stewart.
Grover Stewart as a DT has had 70+ total tackles in 2 of the past 3 seasons.
Colts whole DLine is good.
Even Ray Lewis would have a hard time behind this Bengals Dline.
