If the celtics have the number 5 spot, i would pick Randle. I would have a hard time passing him up at that spot.
Maybe they get lucky and use that pick to help get an established star, or trade down to around 8 and grab Gordon, or down to 10 and grab Hood, and get another asset to go with those drop down trades.
But if the celtics were to pick up Smart i am not sure what to do with him. I am not convinced he is a point guard yet, due to his lack of court vision and creativity for others, as well as the lack of shooting. I might actually keep him and play him at both guard positions with Rondo and Bradley and let him develop.
The order of picks in the 5-12 range are really debatable.
Anyway, I'd keep Smart.
