Simmons impressing and Maker doing okay according to CBS.
"Thon Maker measured well at 7-foot with a 7-3.25 wingspan, plus has put on some weight to get up to 218. He looks bigger, and with his broad shoulders it looks like his frame would be able to stand another 15-20 pounds. He's working with the big men here (his perimeter skill level has led some to speculate if his future is as a massive wing a la Kevin Durant), and looked pretty solid during practice despite Labissiere getting the better of him. He made a couple of 3s, and used his length to block a few shots in the lane. It's fair to say though that he still doesn't look totally comfortable in the post with his footwork, and that will be the biggest place for him to work to improve."
