On the flip side, they're probably all competing for the same spot in camp, since I don't see moer than 1 of them making the opening night roster unless there's injuries. So maybe they each think "let me get a leg up on the competition"...I doubt they play all the games, but each of them might get 1 or 2. But they at least are in camp practicing and trying to make a good impression on the new coaching staff.
