Look at the dates on those fights.

I dunno who Matthew Greer is, but somebody should have taken better care of him than that. How do you let a guy who got dropped 3 times and knocked out by Wilder fight Ruiz 2 months later?

[SN!PER]

That fight already happened

[Malvado]

Just shows how limited amount of fighters this division had at the time even if they were just starting out, at least the heavyweight division got more stacked with time while they were stepping up but now many are near retirement such as Chisora, Fury, Joyce, Ortiz, Whyte, Wilder, and even Usyk himself whose 35 years old currently. (5 out 7 already planned retirement)
