It’s not suggesting intent to murder. It is suggesting intent to make a ridiculously unsafe play. The way his feet left the ice and the motion of his legs made it look like he either got turnstiled, or was going for a big hit, realized he didn’t line the player up correctly, and then tried to take, as you said, a “big leap” as he was chasing a hit that he was behind on. Which is a dangerous play and resulted in his skates being unnaturally high off the ice.
It’s not a wild assumption, and it’s not crazy to investigate or have the conversation. We see players make unsafe plays in an attempt to be unnecessarily physical often, and it’s something that needs to be coached out of the game.
