07:20 AM ET 09.16 | Monday is moving day for Nathan MacKinnon, this past June's No. 1 overall draft pick, but he won't be scooping up a swanky loft downtown or a McMansion in the 'burbs. Instead, reflecting that he just turned 18 on Sept. 1 and is the contemporary of Americans in the early stages of their senior years of high school, MacKinnon is moving into the area home of veteran goalie Jean-Sebastien Giguere, 36, and his wife, Kristen. In effect, the Avalanche rookie is becoming the fourth Giguere kid, joining Maxime-Olivier, 6; Luka, 4; and Felix, 1. "I'm excited," MacKinnon said [Sunday] ... "I think it's good for a young guy like that to be in a family environment," Giguere said of MacKinnon. "But sometimes, he will need to have some freedom as well. I'm not his dad."
