What team other than the Suns are guaranteed to take Morant over Barrett at #2? Cleveland has Sexton and Atlanta has Young so the odds of them going for Morant are probably the lowest. Washington is paying John Wall a boatload over the next 4-5 years so they would be foolish to draft a PG since Wall is virtually untradable.
New York is rumored to make a run at Kemba but they always strike out so I doubt they change their draft plans based on a possible free agent acquisition. New Orleans has Holiday and Memphis has Conley but either of them might go after Morant because they are rebuilding and they can trade their current PG. Chicago could go either way.
So I'd say Atlanta, Cleveland, and Washington are the teams we should be fine with drafting ahead of us. New York, Memphis, and New Orleans aren't teams we want ahead of us but it may still work out. Chicago is the only team I really don't want ahead of us because I think they're most likely to go after Morant but they're not a lock.
Minnesota, LA, Charlotte, Miami, and Boston all have very low odds of moving up. Maybe Miami goes for Morant but Minnesota has Teague and Tyus Jones under contract. Charlotte will try to resign Kemba and drafting Morant basically pushes him out. The Lakers and Celtics would probably be more likely to trade their pick if they move up rather than keep it.
