You always have to go about it lightly, but there were a lot of changes being made and kindly trying to push some upperclassmen and some non contributors out of the program, all so he could fit more of his own guys. He had a bunch of post-mission flips, plus actual transfers and yes, JC guys.
By 2017 he had 7 transfers, 4 or 5 JC guys. Plus a few handfuls of both regular and post-mission flips from other schools. You seriously don't think he immediately started trying to improve the 85-man roster?
