Floyd could have won the lineal title at 147 3 different times. Shane Mosley was lineal champ after beating Oscar Vernon Forest beat Shane Mayorga beat Forest Spinks beat Mayorga Judah beat Spinks Baldomir beat Judah Floyd beat Baldomir Then when Floyd retired, Cotto, Margarito and Mosley all fought eachother and Mosley came out in top and was the man in the division. It can be argued that Floyd won the title from Mosley in 2010. There's also an argument that Floyd won the lineal title in 2013 vs Guerrero since the number 1 guy was Floyd and number 2 guys was Marquez who Floyd already beat.
fact is mayweather didn't win the lineal at 147 he retired and duckeed the fighters magro was cheating so when shane beat him he won nothing
Bradley and Pacman are the guys to beat in the welter division , Not Guerrero. Floyd beat Guerrero for the vacant lineal crown.
Lets try this again. I know you're a little slow, so I'll copy it again for you Shane Mosley was lineal champ after beating Oscar Vernon Forest beat Shane Mayorga beat Forest Spinks beat Mayorga Judah beat Spinks Baldomir beat Judah Floyd beat Baldomir
