One thing that really stood out to me in the draft was the number of walk-ons that ended up high draft picks. You had 3 first rounders, including #1 overall pick Baker Mayfield who were all walk-ons, and then the first pick of the 2nd round Austin Corbett was a former walk on as well. Then later in the 2nd round you had guys from UTEP, South Carolina State, South Dakota State, and Sam Houston State all get drafted. If you just take the former walk-ons and the small school guys, you've got 10 of the first 64 picks that were available to just about any power 5 schools. It's an even bigger list if you assume guys would take a power 5 offer over Memphis/UCF level schools. As much as recruiting gets covered, there is still a pretty significant percentage of elite football players that slip through the cracks. I know Iowa has put quite a few former walk ons in to the NFL and Wisconsin has recently as well. It would be nice if Minnesota could join that party and start to identify/develop some kids through their walk on program. I believe Marcus Sherels is the only former walk-on Gopher that is playing in the NFL though Isaac Fruechte bounced around the Vikings/Lions practice squads for a while and I believe he was a walk-on as well.
To go two drafts in a row at a power 5 school and produce a total of 1 NFL draft pick (a 7th rounder at that) is not a recipe for success.
As for the Vikings pretty bland draft in my opinion. Hughes is likely the nickel as a rookie, is he that much of an upgrade over Alexander who will be in year 3? O'Neill has by most accounts a high upside, but is almost uniformly believed to be a project that's not ready to start in year 1. The best case scenario for Holmes is probably a rotational DT in year 1 and for Conklin his best case scenario is probably as a situational TE in year 1. Outside of Carlson (is he going to be a big upgrade over Forbath at K?), it's hard to find an immediate starter in the group. I don't dislike the draft and it could look very good in a year or two, but for a team that's Super Bowl window is open now, it doesn't seem like they added much immediate impact.
