The Minnesota Vikings followed a theme during this year's draft based on a philosophy that has paid dividends in the past.
Find the best athletes with the biggest upside and highest ceiling for potential. Let the rest (i.e. developing into an NFL player) take care of itself, whenever that should happen.
Sometimes players drafted below a certain spot in the first round are characterized as "raw" or "projects" -- prospects whose development could take several years before they're ready to play at a professional level. If a team doesn't have a pressing need at a position, the benefit of getting these types of players into a system and letting them develop over time could yield success down the road.
