While two wrongs don't make a right, Palhares is now fighting in the sketchy orgs because of his history of holding submissions too long. The biggers orgs don't want him. Call it karma or simply "actions have consequences." And I'm sure those fighters are willing to bend the rules (if they can get away with it) to avoid having their own knees cranked extra hard. I recall Meek beating Palhares in a questionable fashion as well.
I wish we could've seen Palhares vs. Askren in OneFC, though. He's a tough style-match up for Ben, especially a few years ago before he'd taken the extra KO damage.
