I think Tyne's skillset is not "running an offense" in the mold of Gilyard or Jeff Myers or Ungerer. He's much more Blake Francis and Kendall Anthony in his offensive approach (but a worse shooter). When he looks to attack, he's looking for his own shot, not looking to open up the defense for someone else. He's very, very poor at pick and roll (can't get the pass away, can't shoot off the dribble, and on the drive often gets too deep and gets his shot blocked).
He seems much better when he is not the primary facilitator; I don't think it was coincidence that his improvement occurred as B. Artis was getting healthier and playing more. B. Artis was much more a facilitator.
And just to be clear -- I still like Tyne as a player and think he was one of the few guys on our team last year that had A-10 level athleticism and ability. I just don't think we can have him as the primary facilitator running the offense. That's not his strength, and we shouldn't be force-feeding him to do it just because he's short.
The guys running the offense will need to be Johnston and/or one of the freshman guards. It can't be Tyne if we're going to be good.
