First off that "monster jam geek" is a complete and utter moron.
Secondly if you actually watch Dennis's flip in racing, he lands on the left side of cage, not the right which is where it collapsed. Trying to use an image from a video of something that is in motion is to be expected from someone of such stupidity. Here is a screen cap of the video board at Tampa while he was trying to refire, the only thing that shows any kind of "damage" is paint scuff of the formed plating they use to cover the entire roof. The A pillar bar is not even bent, now I am not saying that the bar was not structurally perfect but use your brain people. Feel free to pass this along to monster jam dumbass as I refuse to get twitter because of mouth breathers such as himself running rampant on there.
