COLLEGE PARK, Md. — It's no accident that Maryland linebacker Demetrius Hartsfield leads the nation's seventh-ranked defense in tackles and sacks.

Hartsfield — affectionately called "Meat" by his coaches and teammates — works hard on the practice field and in the weight room. He also spends countless hours each week studying film.

Terrapins coach Randy Edsall says of Hartsfield: "He wants to be good, I think that's one of the things that's very important."

Hartsfield had 10 tackles in last Saturday's 19-14 win over Wake Forest and sealed the victory with a fourth-down sack. He was named Atlantic Coast Conference linebacker of the week.

Hartsfield has an impressive resume off the field, too. The fifth-year senior already has his diploma in criminal justice.

Maryland (3-2, 1-0) travels to Virginia (2-4, 0-2) on Saturday.
