Although impossible to accomplish I have always thought it would be great if the NHL would adopt the international size rink to allow more room for skating. The players are too big now for the NHL rinks.
The NHL actually negotiates this every Olympics - the NHL almost demands a regulation NHL rink or they won't show up - only Russia had the clout a couple Winter Olympics ago to tell the NHL to go pound sand and Sochi used an Olympic sized ice surface
There was a huge push in 1984-88 to have NHL rinks be Olympic size as the rink size debate had been around forever.
Montreal always had a rink that was larger than most NHL teams' home surfaces and Toronto had what is today considered standard NHL regulation size 200'x85' Montreal Forum was about 200'x90'
The Olympic size rink has been 200'x100'
Take today's NHL rink and imagine have 7.5 more feet to maneuver when you are at the side boards...would basically be the entire bench area and maybe even a couple feet behind as it is some 15 feet wider in total
Makes a HUGE difference in the corners as the radius is gigantically larger
Calgary and a couple other rinks built around that time were designed to accommodate an Olympic size ice surface
Bettman hated the idea because of the loss of seat revenue
There really is no debate as to the bigger ice surface would promote a better game
The question is who is/was going to pay for it; neither the owners nor the NHLPA wanted to "eat" the decrease
