First of all,I build a SF that now plays in ACBB as starter for the team with the third overall record of the league,and I don't train a single week handling as primary skill
(5793989)But,as more important fact,you have to think a minut about what the a SF need.As First thing,you have to give him a primary attack and defence.So,you had to boost him in IS or JS and OD or ID.Then,you have to give him the other main characteristics JR for an outside SF and Reb for an inside SF.When you build his three primary skills,then you have to give him the secondary attack and the secondary defence,and then the other characteristics that he still miss(Jr or Reb)
So,at this point,you have to give him Od-ID-JS-IS-JR and REB.You miss driving,passing,handling,shot blocking(I'm not considering free throws and stamina that have to be at a certain level for all the roles)
Driving help your player to raise his percentages,passing help your whole team in offensive flow.
Do you agree with all the reasoning?
Well at this point remains only handling and shot blocking,so handling become the penultimate skill to search in a SF
