It was between the Ricky and Madison trade. Either way, we get a QB that has some potential. Carr may not be available and Schaub has only played in the WCO his whole career. Schaub may also not be available because of Vick's propensity to be injured. They may not want to trade him.
But, either way we go via trade for a QB, it'll cost us more than just a player...The ideal thing is to draft a young gun, but almost anyone that we can get would take a year or two to develop. I don't think Saban is in the "wait to develop" mode right now. Now, that doesn't mean that he won't go after a young gun later in the draft.
