Minnesota is doing it. They've proposed staring the season earlier to add extra games and increase period length from 17min to 20min. An effort to keep top kids from leaving.
17 or 20 minute period of Div 3 or 3A hockey would be torture! Could you imagine, it would be a tight 11-8 game with 25 penalties, a few misconducts and kids passing out from exhaustion. Bad for hockey. Should consider 13 minute periods if anything.
