FWIW, Galloway just said that yesterday after practice, Owens ran several 100 yard sprints at what looked like pretty much full speed. He admitted to not being an expert at such things, so he asked a couple of players if a man with an injured hamstring could do that, and the players immediately said "No" and "Hell no".
I know, I know -- Galloway is an old ugly drunk who doesn't know anything.
But this just points out that if you think the other players don't notice or care about such things, you are wrong.
But hey, maybe the other players will just roll their eyes and be fine.
