The Philadelphia Flyers are adding quite the staff under new head coach Alain Vigneault in hiring Michel Therrien and Mike Yeo as assistant coaches. Therrien and Yeo who are very close friends, spent seven seasons together in the Penguins organization and both have close ties to Flyers GM Chuck Fletcher who hired Yeo as head coach in Minnesota and was in Pittsburgh when Therrien got the Penguins to the Stanley Cup in 2008 and has always had an admiration for Therrien who would have been a top candidate for the head coach job in Philadelphia had Vigneault went to Buffalo.
