Not sure that Chong's offense is the barrier to playing time, because as others have noted, the starters rarely feed her the ball when she's hugely open, opting for some ridiculous passes to Stewie on some occasions versus USCar. Chong had the 17 versus Memphis and has been shooting at a 53% in the last 16 games, and 52% on 3's in that period. In the last 6 games she's shooting 69% overall and 80% on 3s. So why are those types of offensive figures a barrier to her playing time? If she keeps knocking down the 3's at 80%, KML may be passing Chong the ball on the perimeter instead of the reverse.
Again, the opportunities that can only come when your teammates pass you the ball to shoot, and unless you're like the poster who asked why she isn't shooting like she did in high school, Chong's offense is really good now, and better than when she scored 20 against Stanford. In fact, especially in the last 6 games, she' shooting better than she did in high school. Possibly that's bizarro, or as j66k says, it's the fact that she is now given the defensive shutdown assignments when previously she was described as defenseless. But bizarro can be beautiful.
