By Tim Healey/DFP StaffAfter the Boston University men’s hockey team’s 3-1 loss to No. 3 Providence College on Saturday, BU coach David Quinn was less than pleased. Poorly timed penalties again did his team in, as BU missed a chance to sweep a home-and-home series against one of the top-ranked squads in the country, and the No. 18 Terriers remained winless on the road.But about a minute and half later, Quinn had more important business to tend to.He walked through the bowels of the Friars’ home rink and up a small set of metal stairs to hug four children, each clamoring for his attention. Quinn’s smile was as wide as it was the day he was named BU’s head coach.Quinn’s four cousins — all 11 years old or younger — were part of a contingent 16 people strong who came to see him at Schneider Arena. Quinn, a Cranston, R.I. native, grew up 10 minutes from Schneider, where he also played plenty in his youth.Saturday was his first time there since being named BU’s head coach in March.“I have a lot of memories and a lot of great memories there,” Quinn said prior to the weekend series. “It will be special. It will be pretty cool to go down there and play against the Friars and be the head coach of BU. That will be pretty neat.”
