Perry's issue was that his style didn't match his best physical traits. He was a KGB-style speed rusher in college but was built like a brick shithouse. You'd like to see him be able to go through a guy with all that size and strength. I think they drafted him hoping they could turn him into Shawne Merriman. Obviously he's not elite like that but has transformed himself a bit into that mold. He's stout as hell against the run and a lot more physical in his pass rush. I think he's a better rusher than his sack numbers would indicate. I hope they find a way to resign him.
One of the fan blogs actually wrote that his problem is that he is assignment unsound and then cannot recover due to issues with lateral quickness.
I have rarely seen him out of position but his lateral quickness does come into play when changing direction or pursuit.
Bud Adams told me the franchise he admired the most was the Kansas City Chiefs. Then he asked for more hookers and blow.
