CHESNUT HILL, Mass. — The Maryland basketball team is still searching for its identity, scouring high and low for any semblance of consistency to carry across multiple games. Short of hiring a private investigator to wade through the mess, the Terrapins (18-8, 6-7 ACC) seem out of ideas and options, especially after a 69-58 loss at Boston College (12-14, 4-9 ACC). Or perhaps they’ve found their identity after all. Perhaps another confounding and disappointing letdown following a landmark win sheds light on the situation. Perhaps these are your 2012-13 Terps, enigmatic until the end, capable of toppling the nation’s second-ranked team despite a season-high 26 turnovers on one night, then laying a dreadful egg before a sparsely packed Conte Forum crowd, many of whom were actually rooting for Maryland.
