DURHAM, N.C. (AP) - Clemson's passing attack looks as though it's still improving entering the final month of the regular season.

The 10th-ranked Tigers had 718 yards - 379 through the air - during their 56-20 win at Duke on Saturday night. Tajh Boyd passed for five touchdowns to match the program record for the second straight game, while DeAndre Hopkins had three TD catches to set a school record for most career touchdown catches.

Boyd says he feels the Tigers are ``starting to peak'' entering the final stretch.

Boyd completed 16 of 23 passes for 344 yards, though he did most of that damage by halftime. After throwing for a Clemson-record 428 yards last week, Boyd has thrown for 772 yards and 10 touchdowns in the past two games.
