Maryland football coach Randy Edsall scored a big one on the eve of signing day: Quarvez Boulware is a Terp.

Maryland added to its recent success in recruiting offensive linemen, adding four-star guard Quarvez Boulware from Friendship Collegiate Academy (D.C.).

Boulware, a 6-foot-2, 285-pound offensive lineman from Friendship Collegiate Academy (D.C.), announced his decision moments ago on FOX 5 DC.

Boulware, a four-star prospect ranked the No. 18 offensive guard and No. 256 overall prospect in the 247Sports Composite, is the 18th known commitment in Maryland football's recruiting class. He's the second-highest rated recruit so far for the Terps, though Edsall is still hoping to land Eleanor Roosevelt offensive tackle Isaiah Prince, the nation's No. 105 prospect per the Composite, when he announces Wednesday at 9:30 a.m..

Sources told IMS Boulware verbally committed during a visit in mid-January, but he told IMS last week he remained uncommitted heading into his weekend visit to Florida. But a year after Florida pulled a last-minute stunner by signing five-star Friendship Collegiate cornerback Jalen Tabor -- like Tabor, long considered a lean to Maryland -- the Gators couldn't repeat the feat.

"The fact that my grandparents can come watch me play is big. They're really close to me," Boulware told IMS last week.

Boulware is the latest piece in an impressive rebuilding effort on the offensive line, for years a weak spot at Maryland. The Terps will also sign 6-5, 335-pound offensive guard E.J. Donahue, a 247Sports four-star from Linganore High in Frederick, Md., and 6-4, 310-pound guard Ellis McKennie (McDonogh/Baltimore). They'll be added to a depth chart that includes a pair of blue-chip prospects who signed a year ago and redshirted as freshmen, guard Damian Prince and tackle Derwin Gray.

Boulware also continues Maryland's recent success -- spearheaded by offensive coordinator Mike Locksley -- recruiting at Friendship Collegiate, which has produced current Terps Gray, Yannick Ngakoue, Jermaine Carter, Albert Reid and Cavon Walker. Before narrowing his list to the final three schools, he was considering offers from roughly 20 schools, including recruiting powers Auburn, Clemson and Florida State.
