I think JT is wrong on the Barcello thought.
That is what I love about Tavernari though, he's willing to speak his mind, and express an opinion.
My oldest son went to a BYU camp in 2017, and JT was one of the "coaches" for his age group. They had several humorous "run ins" and disagreements, but at the end of the week, JT gave him a huge hug, thanked him for working his butt off, and told him to stay in touch with where his basketball career took him.
