If you have not discovered Bob McGinn a Green Bay Packers beat writer for the Journal Sentinel in Milwaukee you should check him out. He's quickly become one of my favorite draft writers (unfortunately you get something like 20 free article reads before you have to get a subscription).
Here is everything he heard from scouts on Alshon Jefferey
All of the WR rankings are here (also includes TE)
Third-year junior from Saint Matthews, S.C. "He is a gifted, gifted player," one scout said. "He's a move-the-chains type. He knows how to play the game. He will battle from Day 1 against physical corners. He's got a lot of confidence in his ability." Another scout said Jeffery had "the best downfield ball-snatching ability of any receiver in this draft." "The big body, the big frame, can make catches extended away from his body," a third scout said. "Those things are really exciting about the kid. Granted, you're not going to get that all the time. You've got to figure out if you've got the right coaching staff and you've got to get the kid to buy into your program. There's risk there, but there's a huge reward, too." Finished with 183 catches for 3,042 yards (second in SEC history) and 23 TDs. Had 10 on the Wonderlic. Tends to get way too heavy in the off-season. "He thinks he's entitled," a fourth scout said. "I don't think he has a driving passion for the game. He plays the game really hard but he doesn't do anything else hard. I don't think he trains well. He's soft." His prep basketball team won four straight state titles.
