Interesting to see how this leads since he apparently is retiring soon. He's a divisive figure in the IWC due to his Benoit rip off style and NJPW junior on speed matches (some love the finisherfests, some watch the .gif of him no selling a superplex and sigh), but this speaks to a bigger issue than "no sold a brainbuster to hit a kick"
Indy promoters are not the most trustworthy people. There are probably some honest ones out there, but I would not assume any one is telling the complete truth without knowing them.
That said, Richards has been increasingly erratic this year. Among other misadventures, he lost a really good NJPW spot for missing a plane flight due to a mystery car accident that didn't seem to stop him from working for ROH. And he doesn't seem on good terms with them, even before the anti-ROH trailer for an upcoming Davey Richards interview was released. He doesn't seem very happy, though it's still a big jump to ripping off people and burning bridges.
There is absolutely no justification for the way they behaved as a group that weekend, regardless of how they felt they were being treated. You only have to look at their pathetic gloating on Facebook to see how their minds work - this was a group of high-school bullies pushing people around and laughing about it.
I look forward (???) to the inevitable Brodus Clay vs. Bromans house techno vs. funk dance off skits in TNA. PS: So is it safe to say that, out of everyone, the person that got over most of all from 3MB was Hornswaggle? Because that's depressing.
