in the real NBA, you often try to etablish your scoring option with giving him new oppurtunities ;)
And in reality the hot hand is a bigger factor, and decision making is probadly a bit weaker because here you had better knowledge of your chanches(most likely a reason why your sg takes so few shots - with 0-5 you could also argue that the engine recognized his off night with an SF who is overmatched too you already play 3 vs 5 which makes it hard to get the ball of for your PG).
