France's Mohamed Mimoune is getting pretty good at this. 1-0 Haroulyoun Babayan 18-0 Ceferino Rodriguez 12-0 Nabil Krissi 21-0 Emiliano Dominguez 12-0 Darren Surtees 12-0 Steven Galeano 76
Daniel Raphael Dubois Marcus Kelly 1-0 DL Jones 8-0-1 Nathan Gorman 16-0 Ebenezer Tetteh 19-0 Trevor Bryan 22-0 Jarrell Miller 26-0-1 Filip Hrgović 17-0 109

+ Israil Modrahimovich Madrimov, now 195. Had that gone Madrimov's way (which it easily could have), he would have: Terence Allan Crawford 40-0 Magomed Kurbanov 25-0 Emmany Kalombo 14-0 79-0 ...and all within a dozen bouts.
I think Canelo is 242-0-4 and is fighting Edgar Berlanga (22-0) next. So, he's right up there. If he beats Berlanga and Crawford next, he cracks 300.
Side note. Ali only beat 3 guys with undefeated records, one of them being Leon Spinks (7-0-1). The other two were Billy Daniels and George Foreman. And Joe Louis only beat two undefeated fighters - someone name Jack Kranz (14-0) and Jorge Brescia (8-0). Both of them finished winning about as many as they lost. Clearly, being undefeated wasn't nearly as big of a deal back then.
Jose Luis Ramirez deserves a shout... Edwin Rosario, Hector Camacho (in my book at least), Pernell Whitaker!
He gets 24-0 Rosario and 15-0 Whitaker, plus a couple 1-0 guys and two 2-0 guys. Camacho obviously doesn’t count as he didn’t get the decision.
OP states number of fights opponents were unbeaten for, but understand if draws have been omitted in practice throughout the thread. No biggie either way.
