I would start Payton Pritchard and have him run the team as the starting point guard, and give him authority to run the plays. Make him the quarterback of the team. Tatum and Brown are too jaded, developed too many bad habits and frankly lack the ability to lead this team on offensive sets. Smart can be the designated quarterback on defense.
Pritchard is experienced enough to run this team's offensive sets. What he lacks in size and athleticism he makes up in skill and savvy. His coach has to give him this authority to run the team. Make him our poor man's Chris Paul in training. He not only stretches the floor but he can create off the dribble. He is our best ball handler by far. He makes mistakes, but frankly should be given the freedom to play through them. Last night until he got tired (after multiple DNPCDs, being asked to go 40 plus minutes), he was stellar out there. With more minutes and experience, he can help right this ship.
