It doesn't relate to football skills, just associating it with past viking receivers such as Percy Harvin. Randy Moss fell to us do to his marijuana use in college. Percy Harvin would have been a top 10 pick as well but fell cuz he got busted with marijuana right around the combine.
Kirkpatrick just got busted with a bunch of marijuana, his stock will most likely drop like Percy Harvin. Dropping him to a late first or early second round pick.
