He's going to be the oldest champion in boxing history. If he beats a much younger Jean Pascal. I am going to rank him as a top 20- 25 boxers of all time. He's going to be rank higher after he retires in the near future.
His best win is againts a Prime Felix "Tito" Trinidad. If he beats Jean Pascal that's going to be his most impressive win in his boxing career.
Beat a couple of future hall of famers:
Winky Wright, Oscar De La Hoya, Antonio Tarver, Tito Trinidad, past his prime Roy Jones Jr, Kelly Pavlik, Glen Johnson.
Beat former World Champion:
Robert Allen, Carl Daniels, Keith Holmes, John David Jackson, Simon Brown, and William Joppy.
His losses are againts:
Prime Roy Jones, Undefeated Joe Cazalghe, Kelly Pavlik, and Jermaine Taylor ( All of them are future hall of famers)
I think he's the 3rd greatest Middleweight Champion of all time after Marvin Hagler and Carlos Monzon.
20 title defenses in the Middleweight Division.
2001 Ring Magazine fighter of the Year
2005 Ring Magazine pound for pound King
He's a former WBA, IBF, WBC, WBO, Ring Magazine, and Undisputed Middleweight Champion of the World.
Former Ring Light Heavyweight Champion
