There's no guarantee that he would have done better or flourished here. Some players take a while to make the leap to D1 basketball competition, some just hit a wall after high school and don't live up to expectations, some transfer and excel, and some stay the same or do worse.
I wish Bethea well. He reminds me of Freeman. Talented player with lots of potential but need a lot of fine tuning and growth. Both could be drafted after year one just on potential, but really need at least two years in college doing the work needed to be able to contribute to an NBA team.
