I'm getting a similar vibe as J-Squeeze on all 3 teams:
Monique and Shawne - strong and competitive team early on, only way I can see them going out this early is due to some other sources than just poor racing, i.e. getting injured, or getting U-turned. And they really aren't THAT big of a threat to deserve a U-turn
Joe and Heidi - another strong team that I can't really see going out do to lack of communication or bad driving. They seem very likely to get U-turned if that shows up in the next couple of legs. Like was stated before, they've gotten the early "villain" edit.
Jeff and Jordan - though they are racing relatively well now, they have stated they argue quite a bit throughout the race, which leads me to believe it wasn't just one leg. i have a feeling, though they'll make it relatively far, they'll fall apart near the end of their race.
3 good teams falling early, allowing 2 mediocre teams and 1 relatively non-exsistent team to pass them up <//////3
