After four games, BYU coach Kalani Sitake is certain of one thing.”I know we are a good team, and we haven’t played our best yet,” Sitake said. “We definitely didn’t play our best (last week).”Sitake and the Cougars will try to raise their level of play on Friday night when they face fellow Big 12 Conference newcomer Cincinnati in Provo, Utah, in their first conference home game.BYU will aim to bounce back from a 38-27 loss at Kansas in its Big 12 opener.After three nonconference victories, including a 38-31 win at Arkansas, BYU became the latest team to be unable to slow the Jayhawks’ high-powered attack. The Cougars led 17-14 at halftime but gave up the advantage only 22 seconds into the second half on a pick-six before yielding lengthy scoring drives on Kansas’ first three offensive possessions of the half.BYU quarterback Kedon Slovis completed 30 of 51 passes for 357 yards with two scores and two interceptions. The Cougars (3-1, 0-1 Big 12) got nothing from their ground game (22 attempts, 9 yards) and allowed 6 yards per carry to the Jayhawks.Slovis has thrown for 1,017 yards with eight touchdowns and three interceptions in four games, relying on the trio of Chase Roberts, Isaac Rex and Darius Lassiter. They have a combined 52 catches and five scores.
