This is not about a denied redshirt (dude played at least 30 games all 4 years). He just wants another year to make bank since there's not really a market for guards his size at the next level. I can't say I blame him there. I'd likely do the same. I'm guessing he wins and the NCAA is once again shown to be the sham organization that it is.
The dad outcome in all of this is the record books will forever have an asterisk with dudes playing 170+ games. I guess this is what people felt like in the 70's when they changed the rules to allow freshmen to play.
