re: How long should I wait to get a qb if I miss out on a top 3 qb.

It really just depends on how your draft plays out and what position you are picking. I for example was the 4th pick. By the time I got to my 2nd pick all of the Big 3 were gone. I took Stafford at the beginning of the 3rd because I wasn't confident that the QBs I wanted were going to be there 20 picks later.
