Yeah a lot of successful wrestler/grapplers in MMA are very physical. They stay on the gas, pressure, mix in strikes during those exchanges, they're explosive, and they stay in the opponent's face from the beginning. Examples of this would include Khamzat, Khabib, Merab, and Oliveira. Even the wrestler/grapplers who don't pressure as much, like Islam, Evloev, and Aljo Sterling are still really physical in grappling exchanges. Nickal looked to be pretty relaxed, took his time, and just wasn't as physical in those exchanges just like he was in his previous couple fights. de Ridder was on the gas that whole fight whereas Bo seemed to just be reacting, which is exhausting.
