Why? IMO is Because if they win on their retirement fight then they WILL WANT TO FIGHT AGAIN. Their clock and greed will come into play. And starts to think that can still take on prime hungry fighters And that is the very reason why they will leave the ring embrassed and hurt their legacy in the end. Very few have walked away on top. Lewis is one... that jumps right into mind who else?
Ali Joe Louis Evander Holyfield Riddick Bowe Mike Tyson Oops these guys didn't. Well, Marciano of course. 49-0.
Lennox Marciano Vitali (?) and Hagler is a good one that doesn't come straight to mind (mentioned above)
Yea..Trinidad ad Leonard are such legeds they can retire after a loss and STILL be at the top of thier game.
