Shazier's situation reminds of a similar situation James Laurinaitis was in. If I recall he stayed because he was having so much fun at tOSU and did not want to give that up so quick. I also recall AJ Hawk advised him to stay because you can only be a senior and big man on campus once in your life so enjoy it. If he decides to come back it will help solidify his abilities and make him a top 5/10 pick. Hopefully he stays and tOSU can continue this special run it's is on.
BTW....I would take out a nice insurance policy, Just in Case.
