CLEMSON, S.C. (AP) - Clemson coordinator Chad Morris says his team's offensive confidence growing with every milestone it reaches this season.

The 10th-ranked Tigers had their biggest offensive explosion since their national championship season 1981, piling up 720 yards in a 56-20 victory over Duke last Saturday. It was the team's sixth game with 500 yards or more this season, a program record.

Quarterback Tajh Boyd established school bests with six touchdowns and 388 yards of offense in the first half against the Blue Devils.

The Tigers (8-1, 5-1 Atlantic Coast Conference) don't figure to have many problems keeping the attack flowing this week either, facing an injury-depleted Maryland (4-5, 2-3) squad. The Terrapins announced Monday that leading tackler linebacker Demetrius Hartsfield will miss the rest of the season with a torn ACL.
