Dude, this is a ridiculous question.
Provided we don't do something unbelievably retarded like draft Brandon ****ing Weeden, the QB we draft needs to be given a chance. If he starts in his first season, struggles are okay. I also think he should gradually show improvement from those initial struggles. You see that in Andrew Luck right now, and it wouldn't be much to ask of the guy we draft.
Geno's the only guy I really trust to set this franchise on the path toward success. If we draft Matt Barkley, I'll be patient, though. I'll give him his time. At least a full season, two if he gets better, so on and so forth.
