During Dave Courchaine ‘s professional MMA debut, he took his opponent into a bear hug and was planning to his next move to get him to the ground. Then he and the crowd at the 2008 “Strikeforce at the Dome” in Tacoma, Wash., got a big surprise. The power went out. “I thought I got knocked out,” Courchaine told MMAjunkie.com (www.mmajunkie.com). “It was pitch black. They turned on two floodlights, and I said, ‘Are we really gonna finish the fight like this?’ It was so hard to see.” The fight did finish, and Courchaine suffered a knockout loss, part of an 0-2 start to his pro career that made him question whether it was worth taking the time away from his roofing company and his family to train. But he continued. Courchaine heads into a June 14 matchup with Luis Santos (56-9-1) at XFC 24 at 15-5 with an eight-fight win streak, including three wins in consecutive months from January to March
