I really don't get the hate Kavanagh gets here. He is a legit BJJ black belt and, by all accounts, a good grappling coach. Nelson trained under him from an early age, as did McGregor. Edmond arguably got lucky when Rousey, one of the most well-decorated judokas of her generation, just happened to walk into his gym. But are we really to believe that Kavanagh, the owner of a small gym in Ireland, just happened to luck out with not one but two fighters? Fighters who were not already established athletes when he started training them, fighters who started with him in their late teens? As far as I can tell, Kavanagh is a decent coach – no better or worse than other coaches of similar gyms. He's no Matt Hume or Firas Zahabi, but there are just a handful of coaches at that higher level.
