Yeah, definitely the fight to make for #1 contender slot IMO (Franky has already cinched the next title shot presumably).
Derrick has fought his way back and Curtis has remained pretty much at the top and needs to stay relevant after that stinker against Volkov. I would forgive him if he managed to put on a good show against Lewis. Doesn't even have to be a finish necessarily, just show more activity and willingness to do damage and not gas the fuck out like he did against Alex.
I'm just not sure how long Curtis could keep Derrick down... and every moment on the feet is trouble. I've been wanting Blaydes to develop an offensive submission game for a while now, but in this case I think he'd actually be better off just sticking to his bread and butter of GnP, especially elbows. Try and cut Derrick early.
