For as long as recruiting has existed (approximately), the NCAA has forbidden football programs from promoting individual recruits in recruiting videos.
P.J. Fleck found a way around that. The NCAA's recruiting manual stated schools could put recruits in their in-house productions as long as it served to advertise a camp or clinic.
Fleck is using the video as an advertisement for Minnesota’s camps, which is allowed per NCAA rules: “It is permissible to post a photograph or video of a prospective student-athlete taken during the normal course of camp of clinic activities within permissible camp or clinic information and advertisements,” the interpretation reads.
Nebraska used the tactic before Fleck arrived at Minnesota, but the loophole gained notoriety when rivals started turning Fleck in, particularly with videos like these in mind.
On Monday, the NCAA didn't exactly close the Fleck Loophole, but they did make it tougher to crawl through. Photos and/or videos can still be taken and distributed of recruits, but they have to come during the course of normal camp instruction and can not contain "focused attention" on any specific recruit or group of recruits.
You can still let your rivals know Johnny Fivestar was on your campus, you're just going to have to be discreet about it.
Monday's news should be taken as a badge of honor for Fleck. He worked the rule book hard enough for the NCAA to change it, joining a club chaired by none other than Nick Saban and Urban Meyer.
