Kansas University's football team continues to address its noticeable holes, picking up commitments from two junior-college recruits and a high school standout who visited over the weekend.

The most notable to local fans is Chet Hartley, an offensive lineman at Butler Community College in El Dorado who originally hails from Kingman.

Hartley chose Kansas after receiving several offers, most notably from traditional power Florida State. He also considered Arizona State and Illinois.

"He's developed a lot as far as technique," Butler coach Troy Morrell said. "He put in the time in the weight room and the offseason program to develop his strength and put on more good weight. He's a very coachable player and has a tremendous work ethic."

Hartley, 6-foot-4 and 310 pounds, may be KU's most valuable commitment yet considering the Jayhawks' immediate needs. With Bob Whitaker, Travis Dambach and Jake Cox all out of eligibility, Hartley will be able to step right in

and compete for a starting job at one of the guard positions. He played left tackle at Butler.

"I think he could play any spot on the offensive line," Morrell said. "I even played him at center in the spring.

"He's extremely athletic. He's probably one of the top two athletic linemen I've had since I've been here."

Rivals.com reported that KU also received commitments from two defensive ends: Aaron Mack, who just completed a two-year stay at Phoenix College in Arizona, and Jenks (Okla.) High standout Jake Laptad.

Mack, 6-4 and 245 pounds, had offers from Kansas and Utah. He originally is from suburban Denver.

"There are very few defensive linemen I have ever seen that come off the ball like him," Phoenix coach Dale Wolfley told Rivals.com. "He has such good speed and plays with so much explosiveness. He's a special football player."

Laptad, meanwhile, chose Kansas over Tulsa. He recently helped Jenks High to the Oklahoma Class 6A state title.

The 6-foot-4, 220-pound Laptad will sign with Kansas in February with the rest of the high-school commitments, while Hartley and Mack both will be able to sign with Kansas on Wednesday - the first day mid-year transfers can sign letters of intent.

Hartley and Mack are expected to enroll at Kansas in time for spring practices next semester.
