How do I improve my fantasy team?

I'm not that good in scoring, FG%, and FT%

PG: Derrick Rose
SG: Wesley Matthews
G: Mike Conley
SF: Nicolas Batum
PF: Anthony Davis
F: Larry Sanders
C: Tyson Chandler
C: Andrew Bogut
Util: Jimmy Butler
Util: Ben McLemore
BN: Brandon Jennings
BN: Samuel Dalembert
BN: Michael Carter-Williams

I think my rebounding should be pretty good, with A.Davis improving, and
Bogut and Dalembert playing more minutes. My 3PT seems pretty good too, and my turnovers aren't too high. Any suggestions on what to do though? I sort of want to switch MCW for an open PG like Mo Williams or Raymond Felton, but IDK :confusedshrug:
