I also think Schaub and Garrard should be included in the trade target QBs, and as mentioned a few posts up, Brooks would be a target if the Saints want to part ways with him, as would Ramsey. Otherwise your assessment of the offseason QB market is spot on.
I agree that Young could greatly improve his draft status if he stays - he definitely has room to improve his draft position.
Holy smokes, I can't believe I keep forgetting about Schaub. I would think the Jaguars would re-sign Garrard as he's more valuable to them as a backup than what I think he'd be worth in a trade involving picks, unless someone overpaid.With his play this year and Vick's injury history, I think it would cost another team dearly to acquire Schaub. Almost definitely a first rounder, maybe more. He looks like he may be worth it though.
Of the QBs that could potentially be playing for another team next year, I think he's is the best.
I've watched Young play twice this year, once against Ohio State and the other against A & M and was
underwhelmed.
