How about you don't just draft a QB high because you need one. That is a great way to waste high draft picks.
If there are better QB prospects coming out next year or even the year after, suck it up, play with who you have, stockpile draft picks.
If you are not in a position to draft one of the better QB's because the team played better than expected, use your draft pick stockpile to move up and take the QB you REALLY want.
From everything I hear, this draft class is pretty weak at QB.
