Which of your players is he, is it Goins? If so, get him in good gameshape, he's been in 7 for the whole season it seems and that's not a way for him to be effective.
How is his stamina? If it's below 5, get that up so he can be more effective.
I'm assuming his PA isn't very bad otherwise he wouldn't be listed as PG, but low PA can also lead to bad shot selection because he's not able to make a good pass so he's forced to take bad shots.
Your offensive flow doesn"t seem bad either, but good flow (good HA/PA on most players) can lead to better shots because assisted shots have a higher %.
His shooting skills are plenty good for your division.
