Glen Johnson would knock Bute out.

I honestly think Bute would toy with him and win an very wide decision or KO and this is coming from a huge Johnson fan. Bute gets hella hate on here for competition but it's not like he can make them let him in the super 6 or force any of the others to fight him, he's trying for Kessler right now and he's tried to unify with Stieglitz but Stieglitz wanted no part, other than that all the other worthy super middles were or are in the super 6 so he had to take the next best available and Bika and Andrade are no pushovers. Brinkley/Mcgee well those dudes were stay busy fights since there was literally no one of worth to fight that was available he had to fight someone to avoid rust and picked 2 top 10 guys and this Mendy character is his mando which he needs to fight because he has a hard enough time getting fights as a champion without a belt no one would fight the guy. Kessler has a far better chance than Johnson at upsetting Bute.
