It will never happen because the NHL is too good for the AHL and they wouldn't dare risk the embarrassment of potentially losing. I've gone over this before with them, they just won't be into it.
I think there is zero chance that a full AHL roster could beat the Stanley Cups champs. The only way the AHL would be able to pull off an upset would be putting together a team of the best 17 AHL players and pit them against the Cup champs. Even then I think the NHL would win.
If this were to happen a 7 game series would be a little long imo, I'd be down to see a best if three where every line plays (third game would be played regardless of series just to get everyone in on the series)
Can't we just lose already so I can look forward to Nhl 17 ... My luck we'd have to play the NHL after I thought my season was over ( Syracuse is holding me hostage to NHL 16 )
