I was thinking of trading Bradley in this scenario for the 12th pick, and draft upshaw At 16. But even if we keep Avery. I think that smart and grant could make much more complete backcourt with both of them being capable passers and ball handlers, grant being a little better. Grant brings a little more size as and length as well. If Grant is BPA I'm OK on drafting him
I like Grant a lot as a prospect, and I'd be pretty happy getting him at 16. His passing ability is really elite, which is something we've been missing since Rondo left. He also has much more ability to create off the dribble than either Smart or AB, to go with great size, quickness, and potential as a shooter (78%FT).
That said, it would leave AB as somewhat the odd man out. It would be OK for a season, but in the long run Smart/AB/IT/Grant/Young is way too crowded.
