Derail Green in the game with 15 and change to go says something. Green has been coming off the bench BEHIND walkons. He's the end of the bench, so Marshall is certainly not trying to run up the score.
A lot of the second half has seen Wessel, Wiggins, and Green, which is pretty much the second unit. It's hard to say who's 1st, 2nd, or 3rd in the post, and therehas tended to be one of the first unit on the court with the second unit.
