If we're talking who he did the most damage to opponents' bodies, I'd go with Chavez. Don't know his opponents' career arcs that well, but he really looked like someone who ruined the guys he fought. Mike absolutely did some damage to his opponent's bodies, but it was just as much about setting up the head shots. The Curry fight is the perhaps clearest exaple of thi, but it was a constant feauture in how he fought.
Got to go with the consensus here. The Bodysnatcher tag fits Chavez more than almost any other fighter.
Chavz hands down, the way he slowed fast fighters down like Taylor, Camacho Lonnie Smith with body shots was just masterful
