You're insane.
It's a lot easier to say 'well I'll come back and get my degree some other time' than actually do it. Unless you don't make it in the NFL I guess.
Everyone thinks he can get into tip-top shape by the combine, but based on what? He didn't recover from a hernia in a year, what makes you think he's ready and willing to get into shape? Makes more sense to take 9 months and get into shape, prove your sophomore year wasn't a fluke, and of course, leave with a ND degree.
He underperformed all year, was over weight, and became a 2nd rounder because of it. The risk/reward doesn't add up to taking the 2nd round money, degree-less IMO.
