I'd like to see a return to "home sites" for the top 4 in PWR with one additional requirement:
"Home" has to have a minimum of 8000 (10000?) seats so visiting fans have some hope for tickets.
Too big you say? Well, in my idea, before the season each team would have to declare where they'll host if they finish top 4 and if that means a facility other than their home rink, so be it. You'd have to have some strategic alignment between certain schools. For example, DU, CC, and USAFA would all have to approach Pepsi Center in Denver. MSU-Mankato, SCSU, and UMD would all probably have to approach Target Center or The X. Quinnipiac and Yale would probably pair up.
What if say UMD and MSU-Mankato both declared "The X" before the season and both are top seeds? Well, in a word, logistics. And a ton of bucks for that rink.
