The Buffs are working on building relationships with other schools in the D.C. area, too.
After signing three Woodson teammates for the Class of 2012, CU has its eye on more D.C. products for 2013, including linebacker Jermaine Carter.
Carter, a 6-foot-2, 220-pounder, played at Archbishop Carroll last year, but is planning to transfer to Friendship Collegiate Academy.
He made an unofficial visit to Boulder last week.
"It was great. It was something new. It was different from home," he said. "The campus was beautiful."
The interest in Carter seems to be picking up, though, so he's in no rush to pick a school.
"I'm not going to make a decision anytime soon, because I'm still getting looks from colleges," he said.
Carter said he met the whole CU staff and has been in routine contact with Darian Hagan.
It helps that CU has built a foundation in D.C., Carter said.
"I know those guys (from Woodson)," he said. "(Cornerback John Walker) said it's so nice and he said I should consider it."
In addition to Carter, CU is also looking at linebacker Yannick Ngakoue, who plays at Friendship Collegiate Academy.
A pair of Woodson defensive backs -- safety Darwyn Kelly and cornerback Jordan Smith -- are also on CU's radar.
