Personally, I am not in favor of banning the lacrosse goal. It is exceedingly rare. It is difficult. It is exciting and attractive to fans. I agree with the "if you are given the time and space and opportunity by your opposing professional hockey players, and you have the nerve and talent to do it against a professional goaltender with the knowledge that teammates, opposing players, fans, and analysts will all roast you if you don't get it perfect, go for it" rationale.
I think the most egregious "highlight" play that should be banned is the "slow walk-in with 12 dekes" shootout attempt. A shootout is, of course, a gimmick, an individual skillset—it is not really the game of hockey, in the sense that there is no passing, defense, teamwork, etc. But it should at least attempt to mirror the realities of the game of hockey, and that is where the slow walk-in shootouts are more of an aberration. There is virtually no situation in a game where a forward would have that much time to execute so many moves. Even when a player has a clearrrr-cut breakaway from the penalty box or from a shot-block on the other side of the ice, they still hustle and get that shot off ASAP. They know there are several opposing players skating hard behind them.
The easy solve would be to add a shot clock for each shootout attempt. I'm not talking about anything too brief—maybe 3 or 4 seconds (it's not as quick as it sounds). Kane's attempt, from picking up the puck to it crossing the goal line, was just under 6 seconds by my count. A shorter timeline would generally ensure that players need to get in there and take a shot pretty quickly. If they elect to sprint their ass off to afford themselves a little more time to deke or shoot, that's their prerogative.
Not perfect, but anything would be an improvement over this bullshit...
