MINNEAPOLIS -- Over the course of the next two days, the Minnesota Vikings will use many of their 30 allotted pre-draft visits on their annual event where they bring handfuls of draft hopefuls to Minnesota at the same time.

The Vikings' annual "top-30" event, which begins today and runs through Wednesday, represents something of a different approach from the way many NFL teams use their pre-draft visits. Rather than bring players to Minnesota one at a time, the Vikings consolidate their visits, in part so they can see how players interact with each other.

Players won't work out for the Vikings while they're in Minnesota, but they'll get a chance to meet with coaches and team officials, and go out to dinner in a group. The players the Vikings bring to Minnesota for the event aren't necessarily at the top of their draft board; the team will sometimes use visits to check on players that might represent a character risk, while other visits might be spent on mid-round prospects they want to get to know better.

Still, there are likely players in the group the Vikings are considering with the 23rd overall pick. Matt Kalil attended the team's top-30 event before the Vikings took him fourth overall in 2012, and the team's top picks in both drafts since Mike Zimmer became the head coach -- Anthony Barr and Trae Waynes -- took part in the event, and the Vikings spent plenty of time before the 2014 draft with Teddy Bridgewater.

The Vikings have taken long looks at two receivers who will visit them this week -- TCU's Josh Doctson and Mississippi's Laquon Treadwell -- as they consider whether to upgrade their receiver group with the 23rd pick. Zimmer was at Doctson's pro day last week, running press coverage drills on the receiver to see how he would react with a cornerback in his face. Though we say this with the caveat that it's tough to trust anything this time of year, it seems unlikely the Vikings would devote large chunks of the head coach's time to players they weren't seriously considering. In any case, the Vikings will gather more information on both players, among several other wideouts, this week at Winter Park.
