Obviously he was just upset that Marvin was completely sketchy and did have a lot of close calls into Webb. I think a lot of racers would have been angry as well, Webb just says it. I'm not a huge fan of him I think he whines about everything when things don't go his way, but some people take things way out of proportion enough to say overly hateful things like Midbeck.
What he did going down the downhill to Martin was dumb though, I get it you want to win, but he was watching for him just to intentionally take that outside and push his teammate out into the mud was stupid. Ya at the end of the day you are paid to win, but I'm sure Yamaha would not be happy paying you to push your championship contention teammate and playing games out on the track. Ah well, he still got passed.
Martin must of have read people think he is a robot on the podium, definitely showed some enthusiasm I thought.
