I don't think it's the injuries per se, but the fact that injuries have limited the number of games Boone and Murray have played in, that is at the core of these comments. I like Boone, he may be the right C choice, but that feels somehow a slight to Dubi, given that Boone has played 2 seasons, one of them being an injury-filled season. Timing of the choice, not the choice, may be the obstacle.
Murray - who knows? Not because he's got x injuries, but because he hasn't been to battle enough to have the stripes looked for by others.
