A couple of points:
1) It's incorrect that Charlie just started playing wide receiver...he's been playing wide receiver since he was a little kid.
2) When looking at his film, bear in mind he was playing on a team with a new Sophomore QB and a new offensive line. A close look at the film will let you observe that he is usually slowing down because the passes are under thrown. Because of the young offensive line, his new QB was being pressured before a receiver could complete a deep post. I think that contributes a lot to the rave reviews he has gotten at camps where experienced QB's utilize his speed and hit him in stride.
3) He is indeed like most kids in HS, growing and improving. He runs track and has increased his speed. He has been clocked on a track with track shoes at 4.42 in the 40 and 10.98 in the 100. That is an improvement from his times as a Sophomore. SEC coaches have had a difficult time believing that speed. He had the fastest 40 time in our latest camp. What goes under appreciated is he also had the second best vertical leap. For a 6-2, 190lb kid, that means he is going to be able to out jump for the high ball in SEC football. He's been in the weight room a lot and is ripped. He's been putting on about one inch per year and 10 lbs/yr in high school. He will end up 6-3 - 200 lb+. Purdue offered him a scholarship as a safety because of this size and strength. His grandfather is 6-5, so the genes are there for him to do some more growing.
4)Kids get listed on college recruiting boards with strengths/weakness's and question marks. All the SEC's schools have told Charlie that they want to see him run in front of them. That's what Charlie did at UT's camp a few weeks ago. He did that at NC State and picked up an offer at the camp. He just ran in front of the Bama coaches this weekend and they were raving about him. So...the question mark on speed gets removed and colleges reevaluate their picking list. I don't think a disciplined recruiting process throws out offers without discussions, and I know Charlie is being heavily discussed.
