If we want Davis he's pretty well ours ,don't know for sure what duration ,it may be in the link I only read the table ,I rate the likelihood someone offers him enough to owe us a first round choice as pretty remote since guys who are physically more impressive will be available in nearly any first round scenario ,but armed with that pick wherever it might be plus our own first we could likely trade up to get the first or second rated QB anyway so in regards to Davis he's a windfall asset if he continue to perform at his current level.
I can't geyt over the FACT that it was not his level of play that prevented us from beating Dallas and they are so highly thought of since our game with them .IMO if Greg Williams can be worth his salt and get this defense playing up to his billing we have a formula that can be formidable this year .
