Vince Young just declared for the NFL draft today. He will probably be taken by Houston with the first pick. (If they don't the owner and head coach might get lynched, Young is from Houston.) If he falls to second, the Saints will definitely take him.
A lot of people have been picking Texas for #1 again next year. That has just changed. Losing Young and most of the offense line at the same time has moved them pretty far back into the pack. The big question facing college football right now is : What does LenDale White do?
With Young coming out, and Vick kicked of the team, Brady is the overwhelming Heisman favorite. If White stays, he will compete for the trophy also.
