I'm sure this is just a terrible troll job but LOL
Gilbert wouldn't beat Douglas, let alone Gegard nor Bader or Vadim, who are much bigger than he is.
Also, Gilbert beating Lovato Jr in a grappling match really....doesn't mean shit. Gilbert is a very accomplished grappler in his own right, Rafael has been retired from active competition due to health reasons, so he's probably not in some great fight shape either.
Not sure how that translates to MMA either way, but, you should probably stop hitting the pipe before posting.
