I'm sorry guys - just saw the rest of this thread. Wasn't trying to give bad information. I had searched for 53 man roster news and came across this link
http://cowboysblog.dallasnews.com/archives/2010/09/cowboys-53-man-roster-predicti-4.html
Didn't realize it was 53 man roster PREDICTIONS
the guy said: "Bryan McCann doesn't make the final cut but he does get through to the practice squad. His speed is his best asset so maybe teams take a chance but he doesn't have size that is coveted.", I was only paying half attention and read too quickly.
Anyway, my bad. wasn't trying to be a bad PF poster
