Hmm, I agree with your points but I don't really think those flaws are necessarily going to bring the teams down. For example, J/T may have relied on physical strength and the express pass to get them through the legs, but they won the express pass because they beat all the other teams. Also, they made up for their flaws tonight with perseverance...
I don't think N/V will win. Can't really pinpoint a reason for that. But CBS hasn't been giving them much spotlight at all, and if media spotlight is any way to judge a team's chances...
On to the women:
I think N/K are physically stronger than B/C. And they keep their cool really well too. Only thing that could possibly bring them down is that they don't appear to be aggressive enough? I mean, they made a crucial move tonight, but I think it was done out of desperation rather than true aggression. In terms of desire to win, I think B/C have an advantage. Remember Dan and Jordan from the previous season?
I used to think B/C were strong contenders and I still do. They've been able to overcome all sorts of obstacles and I really hope they make it all the way! I would be very happy if any of the female teams won.
