Keefe attempted at multiple points to flag down the official for an explanation on why it wasn't called a penalty, since Matthews was clearly cross-checked in a play that is called 99 times out of 100. The response Keefe got from the officials was enough to make you laugh - and not for a good reason.
Keefe was very careful with his choice of wording discussing the call and officiating during the game so that he does not face another hefty fine from the league. Given how terrible the officiating was, though, he should have blasted them a little bit more and just taken the fine. The officials would have had it coming.
