Good post, but we weren't "gifted" that foul ... Carmelo was shoving Pierce around all night, and that one was a blatant elbow throw and right in front of the ref.
There was a ton of calls, (for both teams), that were not whistled tonight, and I personally like that they "let them play", (I hope that trend continues), but that particular foul was just too obvious and too hard to let go ... absolutely the right call.
As far as the Garnett no-call, again, there were plenty of those not called at the other end of the floor, and I think the officials did a good job, (for the most part), of not getting whistle-happy, and letting a physical game be played.
