Biggest shoes to fill: Maryland

Our series continues today with Maryland, which opened spring practice Saturday with one scholarship quarterback. You can probably guess where we're going with this one ...

OUT: QB Danny O’Brien. The third-year sophomore will graduate this spring and have two years of eligibility remaining at a school to be determined. O'Brien completed better than 56 percent of his passes last season for 1,648 yards, tossing seven touchdowns and 10 picks. For his career, the North Carolina native has thrown for 4,086 yards, with 29 touchdowns and 18 interceptions. O'Brien's 22-touchdown campaign in 2010 earned him ACC rookie of the year honors as a redshirt freshman. His 2011 season -- and Terrapins career, at least on the playing field -- came to a close in a Nov. 12 loss to Notre Dame, when the signal caller broke a bone in his left arm.

IN: C.J. Brown. Colleague Heather Dinch has called Brown the ACC's most indispensable quarterback, and with good reason. Brown, a redshirt junior, has five starts under his belt and is the Terrapins' only scholarship quarterback this spring. Maryland has two quarterback recruits on the way for the fall, but until then, Brown has the car keys to the offense, with little insurance behind him. Brown completed just under 50 percent of his throws last season, totaling 842 yards with seven touchdowns and six interceptions. But he proved most dangerous on the ground, rushing for 574 yards, a school record for a quarterback.
