I'm going to have to go back and watch the Poirier-Brookins fight, because I haven't seen it, but I was seriously unimpressed with Poirier in the Zombie fight. It's possible nerves just got the best of the kid, but he looked over-hyped to me. And really, the guy hasn't beaten anyone of note IMO. Brookins included.
I think that's part of the reason I'm liking Cub in this one. He seems refocused after the Llamas lost, and he has some serious power to work with. I think he might be too fast and too athletic for Poirier to take down and control, and I see Cub hurting him and maybe even getting the finish. The seasoned vet takes this one.
