Al Horford.
He already started to show a pretty 15 footer in the latter part of the year, is CONSISTENT, is a team player, and strength will come with time.
JJ and Horford are the two core players of this team. J Smoove is the 3rd player.
Al would take less money to help a team out, which has nothing to do with the topic, but just thought i'd throw that out there.
Anyway, Al Horford will be a very special player in this league, and I'm sure HOF coaches like Larry Brown, Pops, and Phil Jackson would take Horford over Smoove if it came to that.
