It took the former Purdue forward a few minutes to get comfortable. He rushed his first shot attempt and found himself in some bad defensive positions early, but he improved as the game continued.After the early jitters wore off, Kaufman-Renn began attacking the glass as he did at Purdue, especially on the offensive end.
