Yeah, he may be able to just half-ass it like you said after another few years and still cause the division some real problems due to its complete lack of depth.
For those of you that don't know who Jay & I are talking about - Makhov was signed to the UFC in 2015 but wanted to compete at the Rio Olympics (and did) and then planned to cross over to MMA. He had already started training over 2 years ago. He's 6'5 with a good reach (not sure how long) and has competed at the highest levels of international wrestling and had success in both international wrestling styles, Freestyle & Greco-Roman. Over the years he's done this at 264.5 pounds, 275.5 pounds & 286.5 pounds (120, 125 & 130 kilos). He's a lean 270'ish in shape when he cares to be. In Freestyle he's an Olympic medalist, 3x World Champion, Silver & Bronze World medalist and a European Champion. In Greco he's a 2x World Championships medalist and became the first wrestler in 43 years to medal in both Freestyle & Greco-Roman at the World Championships
the same year (2015).
His mandible is huge, as is his head and traps, so I figure it's probably a safe bet that he can take a decent punch when we apply bro science. He can grow a great beard too.
We'd like to see him make his debut ASAP to see what he can do in the UFC's Heavyweight division as he's now 30 years old. Yes, he's an "A-Level" athlete.
