Who cares if they don't get the first QB?
Well, problem is, if they don't get the 1st, they'll likely get theat minimum the 3rd and likely the 4th, unless you want to trade back in.. which I don't think you want to. And with the exception of Roethlisberger as the 3rd (who went 11th overall behind Eli and Phillip Rivers - who btw is no slouch) Dilfer, Brees, Rogers, Eli, Peyton and Flacco all were with the first 2 picks. That leaves Johnson, Wilson and "The Early" Brady years on teams with a Dominant Defense, which we do not have... and Warner and the late Brady years as high powered offense outliers. If Belichik was still the coach, I'd be on board, but, we have a QB guy as coach, so, we need a QB. And for sure, if someone said, "Hey look, that's the next Kurt Warner over there at the Safeway bagging groceries" Sign that guy too, doesn't cost you a thing (And sign Isaac Bruce, trade for Marshall Faulk and build a dome while you're at it.)
Other thing you're leaving out is... experience... so, in the outlier department, Johnson was in his 10th season, and Warner was 30. So that leaves Russell Wilson, who, had a dominant D, Beast Mode and 5 years in school at 2 different Universities as the one young guy, along with Brady... who while taken in the 6th round... the one thing we're not mentioning is... the 8.7 MILLLION guys who were taken before that that aren't in the league. And there is and will only ever be one Tom Brady. (See, now you made me feel dirty) Also, only half of the guys taken in the 1st round - regardless of position- started last year. Point is, you build up the team for 2 years, then you end up having to draft a guy, you've got an OK team around a rookie QB.
Now, my one plug, my advice to you is, go check the film on Wentz... then go read about this kid a little bit, about who he is and what he likes to do for fun. Its pretty interesting.
