Herron seems to run too *****. His receiving numbers at Northwestern seem pretty good. He was the Steelers 7th round pick (#30 or 244 overall). I see him being more like Tony Fisher. He does well on kick teams but you can't tell with Packer kick teams.
The guy has not had enough time to learn the playbook. He will look much better in training camp. He was on the Steelers practice squad all season so he has had some coaching already and not just coming off the street. It was tough for him to beat Parker, Bettis, and Staley for a roster spot.
He may only make the 06 team through injury of others.
