Matt Simon has made some impressive plays in training camp so i wouldnt rule him out, he at least is practice squad material since we have a ton of receivers. I wouldn't count him out of the regular roster just yet though
I keep hearing great things. I've yet to go to camp, but two friends who have gone to every open practice, have talked about Simon's excellent play every time. If he plays his way into thay 6th spot, he'll get it - especially if Smith and Grant won't count against the roster 'til week four.
As for anthony Waters, he seems to be fighting to back-up Fujita as well as Vilma.
