This is sort of neat: ESPN NFL draft guru Mel Kiper has ranked the most "NFL-ready" player on every college team.
You can read his thoughts on the Pac-10 here.
I don't really disagree with any of his selections: Maybe I'd tap cornerback Trevin Wade at Arizona, but quarterback Nick Foles is also a good choice. Oregon fans might pick LaMichael James over defensive tackle Brandon Bair, but James is only a third-year sophomore (though he could bolt for the NFL this spring if he chooses to) and Bair is an underrated college player who is on the NFL radar.
It's also interesting to bounce around among the different conferences.
