Calf kicks will probably not have the same impact, the surprise effect is gone and Conor will prepare for them I predict a grappling heavy approach from dustin for the rematch. He will try to wear mcgregor gas tank out by spamming takedown attempts and clinches and trying to have as much ground control as he can. Thing is, while his bjj is superior to Conor (but mcgregor is still a brown belt himself) i think that their wrestling cancel each other out. Also he can hang in here boxing with Conor as the first fight showed us. All that makes me wonder what will be his gameplan ? If he goes with the same as the first fight that would be a mistake.
