Houston returns 54% of minutes played and 49% of scoring from last season's roster. When you weight it by minutes played, they average 1.4 years of experience among players who see the floor.
BYU returns 79% of minutes played and 71% of scoring from last year. Of courses, that includes Yoeli - who hasn't seen the floor yet. When you weight it by minutes played, BYU averages 1.7 years of experience among players who see the floor.
So he'd be right that BYU has some veterans playing for them. Especially when you consider the amount of scoring that returns and then include a grad transfer like Toolson.
