Everyone is so crazy about getting one of the big three QBs, but answer me one question, if you had a choice to pick Payton Manning or Tom Brady (With what you know now) which would you choose. (Both equally good QB, each in his own way, but one would cost you much more)
My point is not so much, there is a Tom Brady in this draft (same as nobody can be sure there is a Payton Manning), my point is that a QB with good skills can be taken in the later rounds, and groomed to one day be effective or much better. There is no guarantee that any of the top three will ever be one of the elites, or even one of the top 20.
If one of those QBs falls to us, great, but if not, trading up when we are so close, but still have more then 1 hole to fill, would be ridiculous.
