On/Off data is useful. In fact, the On/Off charts that
timvp posts are some of the more interesting data points we get in the season.
But the data is, and can be, skewed...especially by sample size and/or role. Just in the same way that the data shows Cunningham and Pondexter were "useful" when they were far from that.
I'm not arguing that Bertans wasn't useful over the course of the season...his on/off numbers, shooting percentage, and other statistics support that.
But...he was put in a tough spot against Denver. He is not big enough to guard Denver's bigs, and he is not fast enough to guard Denver's wings. This became quickly evident by the eye-test...and frankly, you can crunch numbers all you want but that doesn't change what you see on the court. Basketball isn't a Calculus exam.
He made matters worse by missing his shots, which mostly seemed to be good, open shots.
As a coach, you have to make a choice...and the guy who can't defend his opponent and isn't making shots gets an easy hook.
I still think Bertans is, and will be, a valuable player next season and hopefully next post-season....but in a sample size of 7 games, I also don't blame Pop for making the decision that he did.
