Official visits, official haul. Per the Scout recruiting network site Buffplaybook.com, the Colorado football program has received three more verbal commitments for its 2014 recruiting class.

The three future Buffs are Mission Viejo, Calif., offensive lineman Josh Kaiser, Mission Viejo defensive end Michael Mathewes and wide receiver Lee Walker out of San Diego, Calif. Their verbals bring CU's total commitments for 2014 to 21. All three were in Boulder this weekend for official visits.

The 6-foot-5, 265-pound Kaiser is listed as an offensive tackle on his Rivals profile. He's unranked by the recruiting services and his lead recruiter was Kent Baer. Coach Bob Johnson's Mission Viejo team went 11-1 in 2013, with the Diablos' only loss coming in the CIF Southern Section playoffs against Mater Dei (Santa Ana, Calif.). Kaiser's Hudl highlights are available here.

Kaiser's teammate Michael Mathewes also pledged to the black and gold following his official visit. According to Rivals, Mathewes stands at 6-4, 235 pounds and is also unranked. He had a reported offer from Army with Stanford, USC and Washington showing interest. Mathewes' Hudl page lists a 4.85 40-time, 280-pound bench press and 480-pound squad.

The 5-foot-11, 178-pound wide out with a 4.4 40-time, Lee Walker, graduated from San Diego's Madison High School in the spring of 2013. He originally signed a letter of intent to the University of Arizona, but instead of going the junior college route to get his grades up, Walker stayed in California and hit the books.

Scout's James Bryant reports Walker has the appropriate test scores to enroll at CU in January. CU's Troy Walters led the pitch for Walker and the future Buff was also impressed by head coach Mike MacIntyre.

"Coach Mac is a very interesting Head Football Coach," Walker told Buffplaybook.com. "I say that because I have played for a lot of different coaches and he is very unique in the way he actually cares more about his players as individuals. He cares about his players like they are his family that was impressive to me. He is a more complete coach because he cares about everything. Coach Walters is a great coach, he played wide receiver and was one of the best at it."

Walker was credited with 1,824 all-purpose yards and 16 touchdowns during his senior season at Madison, with 755 of those yards and 12 touchdowns coming as a receiver. Walker's senior highlights are below.
