H.D. Woodson defensive back John Walker committed to Colorado on Thursday, becoming the second player from the Warriors’ Class of 2012 to join the Buffaloes.

Walker chose Colorado over Kansas, Northwestern, Rutgers and Syracuse because he built a connection with its coaches and liked the chance to compete immediately to get on the field.

“I’ve been thinking about them a lot since they offered me and I thought about the opportunity and the exposure and the need and playing in the Pac-12 and playing Oregon and Cal,” he said. “It’s just an awesome place and they have the field I want to study, criminal justice.”

Walker, whose senior season at H.D. Woodson was his only one at the school, had yet to take an official visit. He was planning to visit Kansas, along with All-Met teammate defensive back Kenny Crawley, this weekend but canceled it because he wanted to commit. The 6-foot, 175-pound defensive back will visit Colorado on Jan. 20.

“I wanted to get away from D.C.,” he said. “It’s easy to walk outside and get caught up in a lot of stuff.”

Maryland, Texas Tech and Vanderbilt had also been interested in Walker.

He joins senior defensive end De’Jon Wilson, a 2010 All-Met and former Kansas commit who chose Colorado in November. Walker said Wilson, a close friend, was a big factor in his decision.

Colorado has also been heavily recruiting Crawley, a former Tennessee commit. Crawley’s only official visit so far was to Boulder in early December when he accompanied Wilson on his trip.

Colorado has made a recruiting push into the District. Former H.D. Woodson defensive back Sherrard Harrington is a freshman there. They also offered scholarships to H.D. Woodson sophomore defensive back D’Andre Payne and Friendship Collegiate running back Albert Reid (who committed to Maryland on Thursday).

Walker said now he and Wilson will try convincing Crawley, also a friend, to come to Colorado with them.

“We’re going to work on Kenny,” he said.
