I'll go with 21 pts / 6 rbs / 3 ast / 1 blk / 1 stl.
Jeff is a physical beast and he hasn't played his best ball yet. As noted already, he'll be the primary focus on offense .. . our top option in the LeBron, Melo, Durant, Harden role. He isn't on the level of those players, but he's pretty [dang] good, has incredible tools and seems to finally be putting it all together.
I'm incredibly optimistic about Jeff's future. Next year, regardless of the win totals, will be fun in terms of seeing Jeff improve and mesh with Sully, Bradley, Rondo, Kelly O, etc.
