I believe an injury at that point would have sealed Childress' fate.
I don't like the rumblings I've heard about Donovan McNabb coming to MN. What could the Vikings trade? Draft picks? I don't think they'll let him go for the draft picks the Vikings are likely to have. They can't give up any of their roster, there's not enough depth there. I realize he's not a free agent, but the way McNabb's contract is structured he'll count $10 million against the cap next year. If they trade him or cut him the hit will only be about $1 million. I think he's done anyway, but what do I know?
I think it may be smarter to make a run at Cassel. He's a bit of a gamble, but the upside looks like it could be worth the risk.
Whatever they do, they NEED to address the QB situation.
