Thurman or Porter would make the most sense, Arum has reached out to both "and lowballed". Possible he could've raised his offer for one.
I think only Fury vs AJ, or potentially Canelo vs someone with a pulse are the only 2 fights that could do bigger numbers than this.
Considering it's Bob, it'll be Brian Castano. So Bud can call himself a four-division champ (well, four division WBO champ).
Kind of like Spence and PBC getting Manny out of his belt by administrative means and NOT by beating him so he can fight Ugas to win his third belt. You know the Ugas who has the footwork of a statue. Even at 42 Manny has too much foot movement for Spence
