DEFENSIVE LINE: Joe Vellano, Sr., Maryland, DE, 6-1, 285, Rexford, N.Y. Vellano was part of a defensive line that allowed Boston College to rush for just 8 net yards on 27 attempts. The senior recorded five tackles, including 2.5 sacks to total minus-22 yards, and also forced a fumble that the Terrapins recovered. Vellano leads the ACC and is tied for ninth nationally with 1.75 tackles for loss per game. He’s played a big role on a defense that ranks fourth nationally against the run, having surrendered just 77.6 yards per game. ROOKIE: Stefon Diggs, Maryland, Fr., WR, 6-0, 185, Gaithersburg, Md. Diggs turned in his most productive receiving game this season, setting career marks with 152 receiving yards and 11 catches. The freshman caught a career-long 66-yard touchdown pass, marking the fourth time in the last five games he’s had a catch of at least 50 yards. It was the third 100-yard receiving game of the season for Diggs and vaulted him into 16th place on Maryland’s single-season receiving yards list with 666. That ranks second all-time among freshmen, trailing only Darrius Heyward-Bey’s 694 in 2006. http://espn.go.com/blog/acc/post/_/id/47089/acc-announces-players-of-the-week-17
