A couple things:
#1, the problem a lot of times with players from USC is that in college, most of them can "out athlete" most of the competition they face. Then when they get to the pros, their lack of full football ability is exposed and many don't pan out.
#2-- With McKnight, I would be so hesitent to cut him. I believe he adds a huge element on special teams; he can take any return "to the house" and he gives the Jets great field position a lot of the times. I also believed he was mis-used last year by Sparano; at a time when the Jets were very devoid of special offensive players, Sparano refused to get McKnight on the field as much as necessary. There were many games where it seemed like McKnight was getting 10, 15 yards everytime he touched the football.
But come on Joe; you are in serious danger of not making the team with Goodson, Ivory, Powell, etc and you come to camp and can't pass your conditioning test? Not good my friend!
