Its splitting hairs, but i think Bost is a better POINT GUARD than Bowers. However, Bowers was a better player. Like has been mentioned, Timmy contributed so many things that didn't show up in the stat sheets. I think Bost will be one of the best PG's ever at State and one of the best players. He will most likely do the little things and hit some huge shots for us in the next 2-3 years, just like you said. Also consider, PG was not Bowers natural postition as it is for Bost.
All that being said, I give the slight edge to Bowers if I was picking one of the two to be my PG for next year. If we're looking 2-3 years down the road, I may have a different answer. You can't go wrong with either. Its a fun argument to have. I'll also add that I'm somewhat biased because Bowers is my favorite player to ever play here. Bost is quickly moving up that list as well though. I love to watch him play.
