There's always some sideshow going on that's very entertaining to somebody.
But scorring? If they made the goal about 5 ft wider they'd get up there in basketball's numbers!
Hockey did reduce the size of pads that goal keepers can wear a couple of years ago. The size and increased understanding of weight training and so on has changed the very essence of some of these sports, which makes it hard to know how to tweak the rules without ruining the original intent of the game.
A ten foot basket means something totally different than it did 50 years ago. Same with the size of hockey nets. Same with a 100 yard field. Always a balancing act.
I believe the average score is higher than it was 10, 20, or 30 years ago. It's been a low scoring game for as long as I've been a fan, yet the average scoring is higher now than ever.
Its an exciting game, physical, tough, highly skilled athletes playing at inconceivable speeds on a hard surface. Something for everyone, plus it happens to be the most exciting sport to watch live, at the arena.
