If MCW miraculously slips I would immediately draft him. I'm not sure about Larkin at 16 it'll depend on who else is there.
Even if Rondo is completely healthy I would still restrict his minutes while he gets back, I can see us drafting a pg and him getting minutes immediately.
Yeah, if you like Rondo, you will love Michael Carter-Williams. He will need time to learn NBA defenses and he will need time to develop his shot, but at 6'6" he has fabulous passing skills and ability to run an offense, elite athleticism, excellent defensive instincts and a great ability to go to the hole and finish.
He just has to develop that shot. Having him, Rondo and Bradley as a back court to build a future around would be great, IMHO. Just need some 3 and D guy as well and there you go. Your backcourt is set for the next 5 years.
