It's not a perfect analysis, but I was curious to see how NJ played offensively over the course of his three seasons at Arizona. Using points per FGA as a proxy for offensive performance, I charted each game's total to find the trend line.
X-axis is just the game number in that season; Y-axis is P/FGA. For those who care, the straight line is the linear best fit, while the curve is the second-order polynomial fit.
His first two years, he was fairly consistent in his slump, hitting bottom around the 20th game. This year, he still seems to be going the wrong direction 25 games in, but hopefully we'll be able to look back in a few weeks and see that ASU was the trough. If not, we have a serious problem.
