I think pretty much everyone in here is with you on the "not scouting" him enough during this Draft season. Reed didn't fit the "profile" of a Packers WR. RAS under 8.0, under 6 ft. tall, less than 200lbs. When I looked at that information, I moved on to the next WR. After they drafted him, we are now looking at what he brings, and are impressed with his skillset, and what he can offer the team moving forward. Reed's stock rose by his performance during Senior Bowl week. Lets face it, that Michigan St team wasn't very good this year, so he didn't have a lot of attention in his favor during the season. Participating at the Senior Bowl was beneficial for him to showcase what he could do, and he made the most of his opportunity.I didn’t watch Reed before the draft and I still haven’t seen much of him. So I’m not here to be his biggest cheerleader.
But in answer to your question, it seems as though some people who study WR play really liked him, e.g. Matt Harmon.
But I think he helped himself a lot at the Sr Bowl. If you go back and read reports, he was one of the most oft mentioned guys winning the week. No one could cover him, from what you read.
