I know literally nothing about James Ennis. I like beno and jarnell as people but beno has been awful this season and is a bad fit with the second unit and with Mike. Jarnell was never getting off the bench. Chalmers is a little bit of athleticism and can play along side Mike without completely killing you defensively. Try to get Mike some more shots without having to do all the work.
Not a real needle mover but should work out ok.
