Anyone can do what they want with p4p lists because they are opinion based and theres no official list. Its all someones take on it. People have Bradley below Pac despite beating him so you can make it up as you go along.
Out of these two whos better? IMO its Marquez because I think he won the 1st 3 fights but if I had to rank them Id place Pac higher cuz he officially won and has the better wins outside of their rivalry.
Hope we get closure in December insteda of another close 12 rounder
