As Jermell Charlo sees it, this weekend's blockbuster showdown in Las Vegas for the undisputed super middleweight championship is the moment he has been preparing for since he first turned pro back in 2007.

The crazy part about Charlo attaining the biggest and most lucrative fight of his 16-year career is that he wasn't the first choice. Alvarez, the former pound-for-pound king who has won titles in four weight divisions, was expecting to face Charlo's twin brother, Jermall, in the first of a new three-bout deal with Premier Boxing Champions, but the WBC middleweight champion, who has been idle for two years due to injuries and mental health challenges, wasn't ready to return.

One thing neither fighter appears to be worried about is the size difference between them. While it's true that Charlo is making a dramatic move up in weight, it wasn't that long ago that Alvarez was considered a small middleweight (who would go on to win world titles as high as 175 pounds). Charlo is not only the taller (4 inches) and longer (2.5 inches) of the two fighters, he is huge for the 154-pound division.
