I take it you're talking about Kimbrough
(859410)? There are a number of possibilities (and game shape doesn't appear to be one of them).
He may have just had a few lucky games at the start of the season against inferior defenders. When he showed up on the league leaders board as averaging 30ppg, other teams started defending him better. Looking at the ratings for a number of the games, however (I checked about a dozen or so) this doesn't really seem to be the case, and this just prompts questions from me.
1. He's 28. Are you training him? (it appears you're training C/PF, but you have a team full of very young guys, so I had to ask)
2. You've improved other parts of your team via transfers. Are those guys taking the scoring opportunities away from Kimbrough?
3. He turns the ball over quite a bit and has virtually no assists based on his minutes played and the fact that he's a guard. I'm guessing his passing sucks. Is it possible that such a player is forced to shoot lousy shots by the game engine because he simply does not have the skills to get the ball to the open man?
4. From what I can tell the only changes you made to your offense were switching from playing Motion all the time to occasionally playing Patient or Push the Ball, and lately only playing Base Offense. Have you tried playing an inside game at all? Your inside ratings seem decent, is there a possibility that something like Princeton could open up the outside for better shots?
5. Is your PG finding far more (and better) opportunities to score?
6. There was a suggestion by someone in this forum (Riceball I think) that players may have a hidden "personality". Kimbrough may very well just be a showboat. And since I didn't end this part with interrogative punctuation, I'll do that....here?
7. Have changes made to the game engine made it harder for distance shooters (PG/SG/SF) to hit their shots?
That's all I can come up with. I'm as curious about this as you are, as I have a SF who is going through a similar rough patch scoring-wise.
