Consistency is a trait any football coach will emphasize, but Duke’s David Cutcliffe can talk about uneven performances while preparing for a matchup Saturday against Kansas at Durham, N.C.”If you’re going to do anything and be considered special, you’re going to be consistently good at something,” Cutcliffe said. “We’ve had a major emphasis of working good against good at practice. I think that pays off. Stay healthy and it’ll pay off and continue to pay off.”The Blue Devils (2-1) overcame a season-opening loss to Charlotte to win back-to-back games against North Carolina A&T and Northwestern.In Kansas (1-2), Duke faces a moribund Power Five program attempting to gain footing under new coach Lance Leipold, though the Jayhawks are coming off a 45-7 setback in their conference opener against Baylor.A complete game eluded Duke in each of its wins, including last week when it mounted a 27-0 lead against Northwestern before winning 30-23. The Blue Devils committed three turnovers and drew 10 penalties for 104 yards.Obviously, better execution must be achieved, though Duke did force five turnovers and can lean on defensive playmakers. DeWayne Carter and Lummie Young were named ACC players of the week after each caused fumbles by Northwestern. Young also grabbed an interception.”He’s always been an extremely aware and savvy football player,” Cutcliffe said of Young, “but you got to play fast and he’s going to continue, hopefully, to practice that way.”That could spell trouble for Kansas, which has struggled to click despite seeing encouraging promise from Jason Bean, a North Texas transfer Leipold chose to engineer the offense. In terms of any positives, the Jayhawks have surrendered just one turnover.
