The only questionmark for me is: is Kelvin gonna use heavy legkick approach in this fight? Jordan, I spent a lot of time watching tape on Robert through the years and he is really the ultimate fighter - he just doesn't have holes that current MWs can exploit. He is amazing almost everywhere. He is fast, has hard punches, he is flexible but strong, good grappling and wrestling, can fight backing up and on the front foot... The one thing that he can't do very well is defending the legkick. maybe because of his lean forward, I don't know, but he is very succeptible for these. Gastelum has legkicks in his arsenal. I just wonder if he or his coaches saw that in Robert and if they gonna try to exploit that. If Robert can't move freely he is half the fighter he is normally, and even then he is very good, but he will become beatable. And expecially over 5 rounds, investing in legkicks will be huge.
My personal opinion is that Gastelum is not very cerebral or even a hard working type fighter and we won't see him throwing more legkicks here than he normally does. But I don't know for sure of course, he can surprise me.
