Terrible trade in my opinion. Rondo is a top 3 pg, and we locked him up for a very good price.
Also, I know this is a hypothetical trade....but if the Celtics get knocked by the Miami Heat, it will probably be in 7 or so games in a tight series, and they will never trade their core because they will be contenders next year...especially with a limited season. I'd say they dont start rebuilding until after Ray and KGs contract expired. And they will never trade Rondo, especially not for Josh Smith.
Rebuilding would mean getting jeff green and rondo and scoring a 90+ million FA. It all depends if KG and Ray and Paul will either retire, be bench players, cassell type or washed up starters. Tough to predict these type of things, and I dont think its the right time to predict rebuilding ya know? we are in the drivers seat for banner 18.
