I can agree. It depends on what type of Manny shows up this time. Then we can pretty much guess which level of boxer he can handle for his next fight.
Vargas is young and Pac is not too young so it may be a little more difficult for Pac this time. Also depending on how serious his training is.
Because Pac is older now, he won't be able to KO Vargas in the early rounds. I predict mid to late rounds TKO
