Here are some ideas:
NRG
FNS, s0m, ardiis are all rumored to leave, lets just say hypothetically that all of this is true and they have to build a team around Victor and Crashies.
The most common idea I've seen is johnQT, yay, Marved, so basically OPTIC -FNS +johnQT
another interesting idea if they can't get yay is picking up someone like koalanoob, sym, or pwny.
in terms of IGLs other than johnQT there isn't anyone else really, the next best ones are stellar, flyuh, mitch, and maybe even runi
the most extreme variation is letting Marved call if he gets picked up but I doubt that's happening
100T
Asuna and Cryo are staying for sure, bang might be gone, stellar and Derrek are probably gone. I honestly think picking up some T2 players would be good for them, here's my idea:
Asuna - Cryo - s0m - aproto - flyuh
assuming they get s0m for bang (which is a little unlikely ig) i think aproto is the next best sentinel they can get, of course if they can get FNS then that would be really nice, so if they do then:
Asuna - Cryo - s0m - FNS - eeiu (to replace Derrek cause you don't need an IGL anymore)
other sentinels possiblt worth considering from T2 are moose, dapr, Dicey, and POISED (these are pretty bad options).
SEN
Apparently they are keeping TenZ, Zekken, Sacy, Pancada, so they need an IGL on controller or sentinel.
FNS is the obvious candidate. other less likely options are johnqt, stellar, and flyuh
C9
0 clue, if i were in charge id keep leaf and xeppaa and probably zellsis, if bang is on the market i might get him over jakee, but i think they really can just settle down and keep this current iteration.
EG
trade demon1 for something >:)
TGRD
i doubt theyd make any moves, only thing i see them MAYBE doing is trading jonahP for nismo but thats probably my bias thinking nismo is better. so i doubt they change.
thoughts? what are your roster ideas?
