As long as we're going small, I'd put Brown and Hayward in the starting lineup and bring Smart off the bench first for Irving as the backup PG.
PG: Irving (32), Smart (16), Wanamaker
SG: Brown (24), Rozier (16), Smart ( 8 )
SF: Tatum (32), Brown ( 8 ), Morris ( 8 ), Ojeyele
PF: Hayward (28), Morris (20)
C: Horford (30), Theis (18), Williams, (Baynes)
Smart is a point guard, and Rozier is a shooting guard. Hayward and Brown are starters.
If Rozier pouts, play Wanamaker and Ojeyele.
