Harrison announced his offer from Colorado on his Twitter page.
As a freshman this past season, Harrison led Blinn with four interceptions while also posting 23 tackles and 10 pass breakups.
"I didn't really start until the fifth game, so I had to work my way into that role," Harrison noted. "I really can play both zone or press coverage, but most of my picks came from one-on-one coverage. I attack the ball in the air as if I'm the receiver."
Harrison enjoyed a solid prep career at Atascocita (Houston, Tx.) High School and had planned to sign with Fresno State, but he was unable to get qualified, so he chose the best JUCO program he could find and that just happened to be Blinn.
"I had a really good relationship with coach (Tom) Rocco who was here when I was being recruited," Harrison recalled. "I also really liked what the program here is all about."
Harrison will finish up his two-year degree in December and he will have three years to play two following the 2017 football season.
