Sure, but if you start with a stat that has primarily one problem, then remove that problem, it's probably a good stat.

RPM is just a more heavily iterated version of APM or RAPM - statistical methods of filtering out the impact of opponents and teammates (and coaches, apparently) on a single player's plus minus.

It's no different than the algorithms that went into weighting the different stats for PER, WS, WP, etc, except without the somewhat arbitrary values assigned to those stats, so if you lend any credence at all to those catch-alls, you should have no issue with this one.

And no surprise that once again, you see solid contributors like Amir, Lowry, Fields, Patterson rise to the top.
