Generally I like all the teams to some degree currently. They all have some behavior I don't care for (with the exception of Brian who just hasn't done anything bad in my opinion).
As for the trotters, in general I like them, with two real exceptions. I really thought their taunting of Mika was very uncalled for. As they have noted in 6 different times (between clips and footage) they can just hang behind and beat some one in a footrace. They even use this with the only team they see as any sort of physical threat (Sam & Dan).
Yet here they are knowing they aren't at the Pit Stop yet, making this girl's fears even worse, knowing that even if she did complete the task that they would have absolutely no problem beating her in a foot race. It's not against the rules, but it is very much poor sportsmanship on a team that didn't need the advantage.
I also strongly disliked their blaming Sam & Dan for dirty tricks at the Mud path. Dan can't see him, he can see Dan. I disliked how they promised to use more physical contact against them. They can clearly see how much room Dan takes while running. Flight Time can clearly see the path is not wide enough for two large men to pass without having physical contact. He is the one to make the choice to try and go by him, in a space that does not allow two full sized males to do so). He knows that he would have to push Dan (at least some) to get enough clearance to get around him (I used my frame and my boyfriends against the measurements of the site in question, provided by the owner and we couldn't get by each other and we are smaller then those two men).
Dan says he was pushed (accurate) Big Easy says Flight Time was elbowed (most likely accurate as elbows do swing when you are running and Flight Time does run into him and the area is his side where his elbows would be). But here is the rub. Dan is running is elbows would naturally be going out and back from his body. Its the natural form of running. Flight Time is pushing into his right side where he would natural run into that elbow. To think that Dan is doing anything wrong or not a part of normally running is ludicrous. And for Flight Time & Big Easy to accuse them of deliberate physical contact is also very questionable, as the only racer who knowingly put themselves into physical contact is Flight Time. To blame someone else for that is very, very poor sportsmanship.
Now I do disliked Sam & Dan obsessing about the Trotters, and they do appear to be the only team since Lance & Keri got booted that the guys don't like. And they have accused them of doing things, they themselves have done (as have all the other teams at this point (deliberately following others when you didn't know the way) and for using their status (for what it is worth) to get help (and we have seen them try this, we don't know if they have been successful or not the footage isn't clear).
As for Dan and Sam taking Brian & Ericka's cab, it also is poor sportsmanship, but it also isn't against the rules, and it is something that does occur during the race, sometimes quite often. That and the Oh I didn't see the clue (after you just grabbed one) is probably the two most common things racer due to mess with other teams.
