Kyle Anderson should be the starting Small Forward but how much they play him at power forward could have an impact on the other wing players. The team may need one of these shooting guard candidates to play at the three more than anticipated.
This likely won’t affect who gets the starting spot but it will affect how many minutes the guys off the bench get. Someone like Wayne Selden or Dillon Brooks could spend time at the three if Anderson is playing the four.
All of the candidates are capable players it just depends on who fits in the best with the rest of the starters.
