I'd say the return of the "10 minute rule", to keep people from squatting on picks.
Maybe a rule that if you miss your press conference, you're ineligible in the playoff voting.
Overall, though, I think everything ran extremely smoothly, and I don't think we need to really make any changes. I was a bit puzzled by the call for a dual-commissioner system, as I thought Dons was on top of everything this year.
