After watching yesterday's games, I'll take the Wagner kid from Michigan. Kid was beasting out there against Louisville's bigs.
If you watched more Michigan games, you would hate him, if you're like most Celtics fans. Great kid, talented offensively, but is an incredible defensive liability due to his consistently poor positioning and tendency to commit dumb touch fouls as a result. He makes Olynyk look good in that department.
Imagine Olynyk with worse ball skills and defense. He needs another year to work on that stuff -- I don't think he'll get that necessary court time in D-league or on an NBA bench.
