Because he didn't just add another Yes Man to his bench, he gives himself the opportunity to change his voice. This roster is still young. Guys who aren't playing up to snuff on the defensive end don't need to be on the floor. BYU is not going to win the WCC this year, and it is very unlikely they'll sniff 2nd. So take advantage of this season to establish a new defensive identity, where guys who play hard, fundamentally sound, and within the defensive system are the ones who see the floor. Virtually the entire roster can score. But if TJ wants to stand around and ball watch, sit him. If Nick gets frustrated and starts reaching, get him off the floor. If Yoeli is consistently out of position, replace him. The program needs an attitude change, and there is a very small window for Dave to take advantage of this opportunity, otherwise things will revert to business as usual.
