Shaq was seemingly too good a kid to be the leader some (a lot) guys on this team needed. Leading by example obviously wasn't effective. More extreme tactics were obviously required and some kids that you'd kill to have 22 playing for you because they handle their own business in a stellar manner just aren't comported that way.
None of that is any fault of his own and we all should be pulling for this kid hard to have a Perryman type of NFL career (minus the injuries). At least on the next level he won't have to deal with so much disfunction and immaturity.....unless the Browns take him.
