The point guard position is the only position that you should be playing to be honest Rainey, because the computer AI tends to play around the team system. So you are playing with the Thunder, they wont really pass you the ball to score because you arent proven enough or your not getting in enough 'open' positions. When I mean open, it can mean you being wide open, so that the nearest defender cannot block your shot. Or open as in, being open with a defender close by and then making the extra effort to get past him to score, like with a pump fake move, jabstep, crossover etc. Of course it all depends on how good your player is at this but it should still be essential for a guard, SG or PG.
For Baboons, youve picked the best position because you control the team, you decide if the play will end up with you scoring or someone else and also, you have more of a chance of increasing the grades because you can assist more as well as score. Giving up the ball is very easy and can sometimes be more effective than scoring. My player was very good at this because I decided that I didnt need to take jumpshots playing with Rudy Gay, Zach Randolph, Lamar Odom and OJ Mayo. They were all exceptional at scoring so all I had to do was find the best way to get the ball to the open man. Throughout the season I became better at Layups and my ball handling skills were excellent which meant a simple behind the back dribble was all it took to get past the defender and a free lane to score. I was also 6'7 which is very tall for a PG but I was able to grab rebounds and begin the fast breaks myself. I became a poor mans Jason Kidd, but My Grizzlies got to the playoffs, only to get knocked out by the Spurs in the second round (Tony Parker was way to fucking fast).
