Personally, if we take Smart, I feel that Rondo will be dealt. Why take a PG at #6 to be a backup?
I disagree. If we take Smart, there's 3 possible outcomes:
1. we keep him and use him as the first guard off the bench behind Rondo and AB giving us a solid backup for either Rondo or AB.
2. we pick him for someone else in the draft and trade his rights. (I think this is the most likely scenario if we pick him). I could see Sac as a trading partner as an excellent upgrade over Thomas to pair with Cousins. We'd pick up an extra asset for our efforts (like #8 and other pieces)
3. Rondo is traded which seems pointless since we would have to hope Smart becomes as good as Rondo someday. Might as well keep the real deal since other big name players have expressed admiration for his game and would like to play with him. (I think is the least likely scenario if we draft Smart)
