I didn't even look at the fights for today's event in Dublin, but I don't think anybody expected the Diego Brandao match-up to be a big test for Conor McGregor... it was likely meant to be a bit of an "ease-back-into-things" type of fight for him after being out for so long with an injury.
Brandao is clearly on the chopping block now... with a 4-3 record in the UFC, and going 1-2 out of his last 3 he'll be lucky not to receive a pink slip.
I do like the Dustin Poirier vs. Conor McGregor much better, but I think Poirier gives McGregor his first UFC loss by submission.
