The captain of the victorious Boston College Eagles hockey team walked through a vacant school parking lot Sunday afternoon, trophy in hand and a broad smile on his face. “It’s definitely great to be home,’’ said captain Tommy Cross, 22, a senior and defenseman for the Eagles. The title-winning team arrived outside the campus stadiums after a 4 to 1 NCAA championship victory in Tampa against Ferris State University, hailing from Big Rapids, Mich., Saturday night.
