On the Smart discussion, it's pretty clear he should just be the 3rd guy in that guard lineup of White, Brogdon and Smart. And Smart losing his mind like 5 times since the Break isn't ideal either. What if this sort of stuff costs us a close playoff game?
Smart would be great in the famous Celtic role of 6th man - if he would accept it.
Start White and Brogdon and bring Smart in to jack up the energy and defensive pressure.
Would have to remind him that playing more with the 2nd team would not give him permission to jack bad 3's.
Starting lineup of Brogdon, White, J, J and Horford or Rob.
Formidable bench lineup of Smart, Hauser, Grant, Pritchard and Horford or Rob.
Of course, you mix and match lineups according to opponent and individual player's health.
