I am going back to Rozier. I realize he is a little small, but he is certainly long and that should be enough to limit Porter who certainly won't go blowing by Rozier.
Rozier is also a powerhouse rebounder. Even though he isn't 'big', he gets himself into the lane with authority and rises over everybody. He has done this consistently since I first saw him in a Cs uniform.
And, finally, Rozier has actually been productive when he has played (last night notwithstanding, where he only somehow managed 8 minutes even with most of the game being garbage time). KO and Smart can keep their bench roles and we can even filter in Brown. But, at this point, Rozier is more game-ready than Brown.
