Probably what we should be looking at is not how well these players are performing individually, but rather how well the team as a whole plays when they are in the line up. And, judging by their +/- numbers which I posted earlier. They are not all that bad. Only one game of 6 with a -11. The others were quite respectable even for 1st tier players.
Maybe arguing how well or poorly they play individually is a poor metric and useless minutia. Perhaps, I'm guilty of that too.
