There are numerous QBs in the league worse than Moore, and several of them are starters. I'd put Moore in the same category as Ryan Fitzpatrick and Colt McCoy, guys who are decent QBs on less than talented teams who get dissed no matter what because they weren't high draft picks and because their teams aren't winners. IMO, if their teams start winning, they'll suddenly become "better", especially in the eyes of cretins like the guy who made this list whether their play significantly improves or not.
I suspect that of the 2011 rookie QBs on this guy's list -- all listed higher than Moore -- all but 1 or 2 of them will be considered busts by year 4 of their careers. I have no idea who they might be, but on average, there's 1 good/very good/elite QB in a draft class and maybe 1 other guy who's decent.
