There was a time i've read an article too on Julio Cesar Chavez' road to 100-0, going into his much-anticipated fight with Whitaker, it says he beats Sweet pea by controversial decision and the Whitaker camp cries out, its Meldrick Taylor all over again, win number 97 against Tito Trinidad and win number 100 against Kostya Tszyu and getting knockout by Terry Norris in his 101st fight.
On topic, my timeline would be:
Mayweather losses by split decision to Guerrero on May 4
Calls out a rematch in November, beats Guerrero by decision
Talks were again centered on May vs Pacman, but Pacquiao has to get past Brandon Rios, and he losses, therefore eliminating any hopes of this fight from ever happening.
Finally, Mayweather vs Alvarez on May 3, 2014, Cotto retires because he was the one hoping to fight Canelo. Floyd shockingly losses to Alvarez in a one-sided fight, now 1-2 since signing up with showtime with 3 fights left, Mayweather says im just looking for two more fights.
Floyd beats Lamont Peterson and Devon Alexander in 2015.
