A couple of twists:
Firm are in the same group as TonTons and Heat, TonTons are rebuilding but will be strong with Jackson and Danner. If they can get out of their group they'll do well, but it will be close with TonTons.
JRab didn't make it to Chartres as his passport wasn't renewed in time - it's a HUGE hit for Impact, they still have an insane roster but I think he'll be the difference between 1st and 2nd.
Expendables is basically Dynasty with 4 of them travelling over. I'd guess rotating them with 3 playing 1 resting. Dropping to 2 if they get a good lead, all 4 playing in the latter stages.
Emelya Red Storm have hired 3 US pros.
My top 4 will probably be:-
1. Heat
2. Impact
3. Russian Legion
4. Expendables
