It sure seemed to me like he was moving the ball, creating shots for himself and his teammates, and playing with good energy overall forcing turnovers and making the right play in general. But hey, none of that matters if the plus-minus says otherwise -- despite it essentially being a lineup stat with moving parts that individual players can't always affect. But hey, we see things differently. There's no point in trying to go any deeper now.
The problem Cam is that the guy has been a negative in that stat over the course hundreds of games and thousands of minutes and this season has been no different. Last year was the one time in his career he had a positive net rating and net on/off rating. At some point, shouldn't the player get some blame if after 8 seasons his Net rating is negative AND his Net On/Off rating is negative? At that point, "context" doesn't matter because so many different contexts are applicable. If all the other variables are changing around you, but you still are a negative, then that seems to point to the one constant! But unfortunately it's a point you'll never concede when it comes to DLO.
Sure, however, that ignores the other stats that paint him in a more positive light, which is why I've always argued that the assessment of any player is about much more than any one stat -- if I have a handful of stats that say this player is good, I won't ignore those because this other particular stat(s) says he's a negative. And that's exactly what happens here among a few constant posters.
The larger issue I have with traditional plus-minus and on/off stats is that if we realize they're fundamentally flawed or misleading at the single-game level, due to the lack of context (which always matters), then why is a bigger sample of all these same single-game values any more meaningful? Collecting more flawed data doesn't make the data any less flawed. It just means you have more of it.
You and others hail plus-minus when making your assessments. That's fine. Others like VORP, BPM, RAPTOR, and whatever else is available that matches what their eyes tell them as well as more traditional numbers. And that's also fine. I've long said that the best analysis involves all of them, though. I don't see how that can be argued. But somehow we always come back to the plus-minus talks around here as if it's THE stat, and it's just not -- unless we're talking about the performance of a specific lineup combination.
