In an odd moment during the Bruins’ 5-1 over the Avalanche, Nathan MacKinnon seemingly whiffed on a slash at Tomas Nosek, only to make contact with NHL linesman Michael Cormier. Or did he?

Frankly, it’s not easy to tell. DNVR’s Nathan Rudolph put together a “frame by frame” replay of MacKinnon’s would-be slash (attempted at Nosek, perhaps not connecting with an NHL official?), and claimed that MacKinnon merely struck the ice.

Twitter user Michael Ryan shared the footage of MacKinnon whiffing at Nosek/slashing Cormier/missing both and hitting the ice.
