You know, nothin' for nothin' but Caligula was only a childhood nickname meaning "Little boot." And he was a depraved psychopath. And he wouldn't have beaten Hagler either, who actually conquered Italy, when past his prime.
I like Ennis's chances better than mine against Hagler in his prime.... But that's not saying much lol.....
On second thought this is another outstanding thought out post by @MarkusFlorez99 Gotta go with Ennis by KO under 5 rds. Boxing has evolved too much since the 80s
