The CHL was low-low minor pro hockey. Any team in the current USHL would smoke them. I'd say the top half of the NAHL would still probably beat them, and the other half would give them a run for their money. Yes, they're kids. But, hockey is getting younger, faster, more skilled, a look at any level of hockey would prove that, especially the NHL. And if you think it's becoming softer, the NHL still has a fight every other game (.6 per game) and increased number of hits, becoming more concentrated along the boards and fewer open ice hits.
The NAHL cleaned up its act in recent years, it was known as the Non Advancement Hockey League for a while and it's where big, chippy kids went to fight until they aged out. You would've liked it.
But, if it takes big, unskilled, older players who aren't going anywhere with their careers to sell hockey to these markets, then give them a division in the Federal Hockey League. They'll get to watch staged fights, players on $50 per game chucking nucks, and all of the glorified beer league that comes with "ole time hockey" that we love to glorify so much, although few people want once they see it. And if those teams last as long as these USACHL teams, they'll have a longer life span than most Fed teams.
