Sylvia being 300 lbs doesn't mean he couldn't take a punch as well or better than he did in his UFC fights where they cut to make 265 and Mercer wasn't a big puncher by boxing standards. Mercer's KO power can't remotely be compared to Wilder's, let alone the 48 year old Mercer who was 13 years past his best. How many top boxers have gone into MMA in their primes? And how many of them were KO artists? Someone like Shields has no KD/KO power worth talking about, of course she got ragdolled by an average female MMA fighter (although she beat one journeywoman on her debut). Fury isn't the best candidate for transitioning to MMA because he's not an elite one-punch KO artist. "even pure world class wrestlers and bjj champions have to cross train to compete in mma" If an Olympic gold medallist HW wrestler had a solid chin I'd favour him to beat many UFC heavyweights. Perhaps I'm crazy, along with the bookmakers: This content is protected "No boxer could win an mma match on any level in the ufc" Are you saying that Wilder (on one training camp) would have "zero or near-zero chance" against some short, obese, weak-chinned UFC HW?
