I think a good decision for Tyler as well.
He has NBA talent but I don't think he has shown enough on the floor to put himself high enough in the draft to be a roster priority. Probably a low second round choice or even potential to fall out of the draft.
Come back for a year, keep rebounding and showing spectacular ability at the rim offensively but also show some more offensive skills away from the rim. Hit some jumpers, work a little more outside the paint, and he could move up quite a bit. Also while he is at it adding 10lbs to his frame would help a lot as well.
For selfish reasons I think he is going to do some really special stuff for us next year.
