Offense: A. The Jayhawks played their best offensive game of the season, passing at will on the Cyclones. They also survived another game without starting running back Jake Sharp.
Defense: F. You can't give up 512 yards to Iowa State and expect to compete the rest of the Big 12 season. The Jayhawks had one sack and gave up 219 rushing yards.
Special teams: C. No big plays out of the special teams for another week. A missed point-after in the first quarter could have been huge.
Coaching: C. The Jayhawks were not prepared for Iowa State's spread-option attack despite having two weeks to get ready.
Player of the game
Todd Reesing completed 37 of 49 passes for 442 yards and four touchdowns. He also ran for a touchdown.
Reason to hope
The Jayhawks' offensive line gave Reesing one of the best days of pass protection he's had at KU.
Reason to mope
The secondary looks to be regressing. KU coach Mark Mangino said that he would consider simplifying his defensive looks in the coming weeks.
The Jayhawks play at Colorado, a place where anything can happen. KU has won three in a row against the Buffaloes.
Sharp day to day — KU coach Mark Mangino said that injured running back Jake Sharp, who has sat for two straight games, isn't ready to play.
"We're kind of going day to day with him," Mangino said. "He's just not ready, and we don't know. We're hopeful that he'll be ready for Colorado, but our medical staff said they're not in a position to say that because the healing process for him is not moving rapidly."
Freshman Toben Opurum carried 24 times for 98 yards and a touchdown in relief of Sharp. Mangino also praised Opurum's pass blocking.
Etc. —Receivers Kerry Meier and Dezmon Briscoe are first and second on the KU list for career receptions with 167 and 165.
