JamRad are the only team who I could see upsetting the likely podium. While I like Metelkina/Parkman and think that both Georgian teams have a ton of potential, they aren't there yet and their ceiling is lower than JamRad right now. However, JamRad are inconsistent as heck so they could just as easily finish behind both MetPark and WalMich. Who knows?
If we thought there was a big drop off after the Russian/Chinese pairs, there is just as big of a drop off in the overall quality/consistency after the American/Japanese teams.
