The reason someone can vote from the Rams (I wasn't one of them) was because we haven't seen some of these guys play.
I mean put up the 1999 Rams 4 months before the pre-season started and compare them to any offense in NFL History and then put up the names:
Holt (Rookie), Roland Williams (Seriously), Bruce (legit), Faulk (legit), Warner (who?), Hakim, Proehl
So long as Everett, Kupp et al haven't played a down it is theoretically possible that they turn out to be much better then the skins. That said . . .. not likely.
