Dempsey imo. Peter was too hittable and he didn't exactly excel when he fought former MW James Toney. Don't get me wrong, stylistically totally different, but it showed that a MW can beat Peter.
Dempsey never fought anyone near as strong and powerful as a prime Peter.... Despite what shortcomings Sam might otherwise have had.
I thought that Peter owned Toney the second time around. And James weighed 234 and fought a cagey, counter and retreat fight most of the time, not something Dempsey was renowned for.
Good, modern athlete genes. His problem was it all came too easily and he got lazy and unmotivated. Typical powerpuncher pitfall.
Hard to say, but his traps look pretty overdeveloped which is a big red flag. Maybe he just went to Canelo's butcher.
