His recent losses are to Nick Diaz, Rory MacDonald and Frankie Edgar. All world class fighters, two of whom outsize him by quite a large margin.
He hasn't lost to any dudes his size not named Frankie Edgar.
Lentz is a solid grinder, but he's had trouble with most of the top shelf BJJ guys he's faced and has major defensive flaws in his striking.
I don't think BJ will be fighting for the title again, but if he picks up the right matchups like this one, he'll be able to pick up some wins and remind everyone why they loved him in the first place.
Have they actually announced who he's fighting yet since Lentz backed out? Lentz trash talk was funny at first, but it is starting to wear on me. I'd like him to take his beating soon.
