I move my SF/PG/SG around depending on what the other team has, they all can play the other positions, my PG and SG are great defenders, so if say theres a team that has a weak PG on offense, I'll move my SF to the PG (my SF isn't a great defender) and I'll put my PG on their SF not many teams in lower divisions have good offensive players in all 3 of these positions. The main thing is scouting, I had my SG out for 3 weeks now... Had a 3 game skid, bounced back won one without him, and lost another..
What you need, is a scorer, rebounder, all around defender, a guy that can dish it out, and the all around 6th man.
