Jordan Davis was a 3*. I think some of these 4* and 5* kids attend a lot of camps and get noticed by recruiting media. Those who don't camp get overlooked. Also, how many of these high ranking recruits mature way earlier than their peers and dominate for a while until the pack catches up. Identifying raw talent is where the Sabans, Smarts and others seem to excel.
FSU still hasn't recovered from the sorry state of the offensive line Jimbo left them with, which had started deteriorating while he was there. Interesting that the O-line is a problem at A&M.
