Mark Stoops enjoyed much of what he witnessed in last weekend’s 31-0 win over Youngstown State, but the Kentucky coach still was far from thrilled.The eighth-ranked Wildcats (3-0) will try to author a more poised overall performance Saturday when Northern Illinois (1-2) pays a visit to Lexington, Ky.”After reviewing the film, (I was) really kind of disappointed and a little unhappy with some of the undisciplined play that we had this past week,” Stoops said. “Not to take away from so many players who did a great job. Defensively, it was a very good effort once again. Offensively, there’s some things we’ve got to get ironed out. Just felt like it was a person here, a person there.”Perhaps the Wildcats’ supposed sloppiness would not be such a big deal if the team was not facing extremely high expectations this season.”Undisciplined play,” said Stoops, who broke Paul “Bear” Bryant’s previous school record of 60 victories a week earlier at then-No. 12 Florida. “Any time you have 10 penalties, three turnovers, four fumbles and you do that at home, it just shows you that the attention to detail was not there.”Kentucky’s offense truly shined in just one quarter against Youngstown State. The team was blanked in the first quarter and held to 10 second-half points. Only a 21-point second quarter provided a steady stream of highlights for the Wildcats offense.Will Levis threw for 377 yards and two touchdowns (also two interceptions) and ran for another score. Dane Key (six catches, 90 yards, TD) also had a strong offensive performance, while on the other side of the ball Carrington Valentine registered two passes defensed and an interception.”Outstanding effort by our defense,” said Stoops, whose team has allowed a total of 29 points through three games (9.7 per game, tied for 12th fewest in the country).The Huskies could pose a challenge for the Kentucky defense as they have scored 32.3 points per game over their first three contests. They came up short against Vanderbilt their last time out, dropping a 38-28 decision in which quarterback Rocky Lombardi exited in the second quarter with a leg injury.
