With Tatum (F), JB (wing1) and Hayward (wing2) as primary offensive options, the focus on the remaining players should be on defense and facilitating.
If Smart is the starting PG, you have toughness and defense and hopefully he can grow as a facilitator.
Then an athlietic starting Center that can defend the paint and grab rebounds would round out a nice starting 5.
Would still need to add a consistent bench scorer or 2.
