12 team H2H 9 Cat daily league - in first place and feeling good about my team, which is punting assists

Want to pick up Devin Vassel because I think he's got a chance to be really special by the end of the year. I'm just not sure who to drop from this team:

PG: Melton, Kemba Walker

SG/SF: Jimmy Butler, Jerami Grant, Hawyard, NAW. Hart, Duncan Robinson, 

PF/C: KAT, Myles Turner, Richaun Holmes, Horford, Jae'Sean Tate

I could drop Melton but I am light on PG eligible players and I like his future too. Duncan Robinson has been slow and Miami is deep but he's likely to rebound. Jae'Sean Tate and Hart provide nice REB from the SG/SF spots.

Who to drop? Nobody? Could try to wait through next week since the Spurs play twice but worried he'll be scooped.
