Why is everyone so hell bent on getting a quarterback this year? I get it. I get that having a solid quarterback is the foundation of building a team, but let's not pretend like Miami is a quarterback away from being competitive. There are a lot more things that have to be done in Miami before they can become competitive. At nine or eight, people are advocating trading the farm to move up for RG3, who I don't think will amount to much. And then there are those who advocate signing Flynn, who isn't proven, either, and would cost a lot against the cap.
Simple solution: why not take care of the offensive line and defensive holes this year, and trade down if neccesary, stocking up picks as ammunitions to trade up for a quarterback next year. Until then, the team should be fine. There is no one single formula to building a team, and being so quarterback-focused this year could come back to haunt the team. You make the best of a situation if you don't get the guy you want, rather than settle for the guy you might not want.
Besides, long-term wise, waiting for a new QB in 2013 is much more cost-effective than signing Flynn or trade up for a quarterback who wasn't that highly-ranked in the first place.
