One thing I don't understand from reading those boards is that a lot of them seem to think Sanchez is head and shoulder better than Rex. I'm not saying Rex is good, infact, he sucks as we all know. But is Sanchez really THAT much better?
Excuse the double post but I wanted to reply to G. on this.
Rex is not a very good QB overall. He has his "moments" as we've seen recently but his downsides can be, shall we say, "stab in the heart" dramatic? His reputation has grown, however, based on the inevitability of these downsides and the Jets fans, like many others I've read have simply categorized him as abysmal.
I think another part of it in this case is their frustration with the Jets under-performing this year. The tone throughout most of the forums is one of serious disappointment possibly due to the raised expectations due to the proclamations of the other "Sexy Rexy" about potential SB appearances.
IMO, Sanchez isn't really all that good a QB either.
