Thor would have to take Supes out quick and that's just not going to happen he could take him out but not quick. And Hulk can be BFRed by GL plus he's limited to the ground ( yeah he can jump but the others can fly and they're faster) then it's 3 on 2 and I'm a huge Thor fan I also like Sentry but they aren't beating those 3 if they fight smart. The only way Team 2 wins is if Orion's pride get's to him and he fights Hulk on the ground h2h.
depends on how the Superman-Thor fight goes.
Hulk would rip Orion to pieces, in little time, but he'd still be of limited use in the other two fights.
Sentry would at the least, keep Hal busy for a while, which means that Thor needs to come help out, and to do that he needs to wrap up his fight with Superman fast.
given the present hype around Thor, I'd say Team Two might pull it off. going by what I've seen of Superman/Hal/Orion versus what I've seen of Thor/Sentry, I'd say Team One wins the majority.
