Your players lose stamina cause it's a usual thing that happen every season on every player no matter wwhat you so about it. I suggest training stamina in the short weeks like the ASG and start off the season. Also you could train that/Free throws if ou're out of the playoffs. Now for experience. Your players gain experience when they play enough minutes (which i a lot) and no it doesn't show a pop. It just go up automatically. when your player gain experience, they're supposed to make better decisions I believe.
