When the exchange of words happened I thought they were complaining that Hebert had picked up his broom ( which he did ) to try and drop crap in front of their own rock to slow it down. According to this story Howard's third was pissed because there could have be debris on the ice for their next shoot. Gezzz, there's 4 of them with brooms, take a couple of seconds and give the spot a scrub, mention it to Hebert on the way down and STFU. That just fired Martin to make the shot. Looks like TSN didn't think it was that big a deal or they would have included it with the highlights.
