I don't think you ever did BJJ in your life if you think Maia chokes Lewis out within 10 seconds. Weight classes exist for a reason, yes technique might eventually prevail over the bigger man and your statement might even be true if Lewis was some random 265pound guy who never fought in his life. But a trained MMA fighter, even a guy with mediocre ground skills like Lewis, who weighs that much more than his opponent? I don't care how good his BJJ is, he's going to get smashed if he goes to the ground. Maybe a slick armbar or kneebar after Lewis gets tired, but definitely not a choke and most definitely not within half a minute.
