If I were Adi, I would want the redshirt. I think he will go pro either way, but his stock would be much higher if he proved he could kick field goals too. Even if he has a bad year of field goal kicking, he still a huge weapon on kickoffs and is a proven threat. It would be a win/win for him if he redshirted, and I doubt the coaches would mind too much. After all, we still have the best kicker in the country next season anyway.
