There's a couple of things that surprised me in this video. #1 is the actual foul on Marcus Smart for allowing Spencer Dinwiddie to get tangled up with him on a spin move in the final minute of a four-point game. The 2nd thing is the refs not calling a tech on Celtics' coach Brad Stevens for yelling at them for over 20 seconds. I'm assuming the only reason the refs let Stevens go on and on about the officiating is because they knew the call on Smart was "soooo baaaaad."
The refs made up for the call by whistling Jeremy Lin, Brook Lopez and Randy Foye for personal fouls against Smart in the following 20 seconds; Smart connected on all four of his free-throws and the Celtics came out with a three-point win.
