Don't think he made 10 but a shout out to Jose Gonzales. From his beginning as a welter in the late fifties until his retirement in the early seventies, he fought a plethora of contenders/Champions with some impressive victories and some losses. This guy has always amazed me. Look at his career on boxrec; what a tough out!!
I was checking him out on a whim yesterday. I know what you mean. Talk about fighting everyone out there.
