He doesn't have his degree yet. He's already said this. Not to mention his father is a former NFL exec and current AD at WVU, so the Lucks aren't exactly want for money. If this proves to be the last draft with the big money, no way you miss out on 40+ million guaranteed. If the CBA does go in effect prior to and sets that rookie wage scale, who knows?
Stanford (and schools of its ilk) are less forgiving with carrying AP/IB credits up from high school than, say, a Florida State. Schools in general have cut back on allowing a ton of credits because they want kids to go for four years. 3 is the max AP/IB credits for at least a couple of schools I know.
