Probably not and that's also the biggest flaw of this whole Synergy thing.
Dynamic Season was a thing of beauty in Live 10
If Synergy is only for online games, BIG Moments and Tonight's Games (whatever that is), how does it truly matter? To me, it's only useful if it's implemented in some kind of season/franchise mode. I want to play a season with a team and merge MY stats and tendencies with the real world ones.
NOW, if Tonight's Games somehow influences standings and stats of the season, so you can have your own version of the playoffs etc, that's a gamechanger.
I honestly believe, for Synergy to have real impact, something like Dynamic Season needs to return. Still dumbstruck it isn't back, it was one of the coolest features in '10...
