I have high hopes for small ball lineups.
Giannis seemed like he turned a corner playing more deliberately in the post during the finals in particular.
There's no need for him to push his body too hard during the regular season of course. However there are plenty of teams with 5's (especially backup 5's) who he could eat up without too much trouble.
That and as Giannis gets older I'm expecting he'll have a KG-like trajectory where he plays more and more center. I figure that'll come in tandem with BroLo being phased out as he ages and Portis (hopefully) becoming a long term front court partner. Bobby isn't as imposing in the paint but is a better shooter and more athletic, though is plenty big enough where idk if anyone would call that tandem any sort of small ball.
