Whatever advice about running the hockey teams you give to Pegula & Black will be ignored. The only advice you should give them is stuff that relates to off the ice.
I don't like the way the Regier ran the Sabres nor the Amerks this year, but they shouldn't be taking fans advice on how to fix the mess. You can say "fire Regier, or trade Derek Roy, or add snipers to the Amerks roster" but they should ignore that. Many fans are clueless about running a hockey team, and if Pegula/Black/Regier listened to every piece of advice the fans gave them, then the Sabres/Amerks would be a mess. (Well, a bigger mess then what they are now.)
I'm just hoping that this year of failure will teach Pegula a lesson about owning hockey teams and gets Regier canned at the end of the season.
