What comes to mind? I was just watching Bowe golota 2 and noticed Eddie futch left his charge Riddick bowe. He ended up winning by dq in 248 of round 9. It was a dismal performance of a weight drained Riddick who looked somewhat powerless and tired and fatigued. His weakest performance all before the age of 30.
Lou Duva has done this on many occasions. Even telling Holyfield to hang em up after losing to Bowe in 1992.
