Well if we go through leg by leg, Maria and Tiffany wound have been eliminated in Leg 4, Lance and Keri would probably still be eliminated Leg 5, Leg 6 was Mika's breakdown, so they survive. Leg 7 was Maria & Tiffany and Brian & Ericka problems, so Brain and Ericka would win. Leg 8 is an NEL. Leg 9 I think they would survive over Gary & Matt. Leg 10 is an NEL. Leg 11 was Globetrotter issues, so they would make Final 3.
Overall, they have a pretty good chance of making it to the Final 3, and a chance to win.
