Even though I think Robert lost vs Yoel in their second fight, his insane durability during that fight cannot be understated. He also inflicted a lot of damage onto Yoel in those fights. Not saying that Kelvin is bad at all but there is a big step up from him to Yoel and Robert. The only question I have is if Whittaker will be himself again or if he's actually done via injuries. Also Whittaker isn't as frustratingly small as Gastelum, so trading will probably look better here.
