Compared to Tannehill? Different strengths and weaknesses but I see Flynn looking better in that comparison, especially for 2012.
Cousins, Osweiler, etc. If PC/JS aren't sold on these guys taking one just to take a QBotF would be silly, especially if it would cost a top-50 pick.
I'm not saying you're wrong because Flynn is an unknown, and without grabbing Flynn I would have been right there with you in decrying a lack of movement on the QB front. But I'm willing to give them a pass now that we have a legit bridge QB on the roster, something Jackson isn't and never will be.
Even if Flynn is just a good backup, it's a serious step up from what we've had on the roster since about 2007 (one weekend in January 2011 excepted).
