Lawrence/Stone have the height advantage.
Weights are pretty much even.
Age not really a factor either.
But what about "experience"? We all know that Scarlett has been in a LOT of fights (check any celebrity fight board). Hayden not as many, but she DID have some TV experience - which is probably comparable to Lawrence's movie cred. That leaves Stone as the "weakest link" - as mentioned in previous posts.
But Stone was ScarJo's tag team partner, so she gets credit for having a 'special knowledge' of Johansson's tactics, strategy, etc.
MY opinion, it comes down to whether Lawrence can provide enough "muscle" to overcome Stone's weakness to the extent it can overcome Scarlett/Hayden's "athleticism". J-Law/Stone are going to have to work well together, because ScarJo/Hayden will likely make a formidable pair...and that's problematic.
IF ScarJo/Panties can isolate Stone and keep her from tagging J-Law in very often, they can win. But if Lawrence/Stone can do the same to the smaller, lighter, Panettiere then they will win.
ALSO, is it "one fall" or the more traditional (i.e., old school) "best of three" falls. IF 2/3 then Lawrence's "fitness" may become an issue. Unlike the other three, J-Law tends to look a little "soft" when she's not "trained up" for "Hunger" games.
Looking forward to seeing how the writer (or hopefully writerS - as in more than one story) handles these issues.
BTW: got these "facts" off the Internet...assuming they are at least close to right:
Scarlett: (5'4”, 125, 34DD-25-36) & Hayden (5'2”, 117, 32B-24-34)
vs.
Jennifer (5'8”, 130, 34C-26-36) & Emma (5'6”, 115, 30B-24-33)
