As for Johnson, he is a 5-10, 180-pound receiver from Friendswood, Texas, who is on pace to graduate in 2013 and be ready to help the Vols this year. If not, he isn't a take, according to several reports. Johnson was a full qualifier out of high school according to this article, but he decided he didn't want to go to any school and felt like he deserved to be on a Division I team.

Looking at his game log last year, Johnson had 5 catches for 69 yards...rushed 1 time for 3 yards...returned 1 kick 60 yards...and had 4 punt returns for 67 yards. Blinn only played 8 games last year and Johnson apparently didn't play in their last 5.
Not sure about this offer but I know next to nothing about this guy.
