“I’ve owned the team for three years now, and I really better understand what an owner’s responsibility is — and it turns out that running a franchise and coaching are two enormous and different jobs,” Ballmer told ESPN. “The notion that one person can fairly focus on them and give them all the attention they need isn’t the case.

There needs to be a healthy discussion and debate with two strong, independent-minded people.”
In May 2013, for the first time in 13 years, Floyd Jr. announced that Floyd Sr. would return as his trainer against Robert Guerrero. While some speculated this was because of the bloody nose Jr. got in an otherwise dominant performance against Miguel Cotto (a change to the more defensive oriented Floyd Sr. over the offensive Roger was seen as logical), Floyd Jr. cited his uncle Roger's health issues, diabetes, and poor vision as rationale for the change. Sr. has remained the trainer of Jr. ever since and trained him to victory in his fight over Manny Pacquiao . 
maybe your’e right but ducking is not also boxing is all about…its only this time that ducking have been committed many times by a talented boxer Floyd, he ducked Castillo for a rematch which in the first fight Castillo was the winner in the eyes of many who watched. Again he refused to fight when Margarito in his prime, its evident when he was interviewed many times before when Margarito especially when Margarito was still a champion. Many past great boxers like Ali, Hagler, Hearns, Tyson, Holyfield and Sugar Ray Leonard knows how many fighters Floyd ducked to fight…evidences were their comments when they were interviewed by reporters.
