Yeah, it's a completely different scenario from Micic. He was entering the first year of the new Olympic cycle wanting to test if he could avoid the difficulty of cutting to 57kg (125.5) internationally. The next Olympic weight is 65kg (143), so in his mid-20s he makes a go at fitting the 65kg weight. He was awful at 141 on the college circuit and gave it up. He's always been a guy who dedicates himself to endless hours of technique work, but not to the long-term weight training and power output building that the strength and speed of 141/143 opponents demand.
Mendez is young, fast, twitchy, still growing, bigger frame...he'll be great at 141/143.
