A closer look at the positions the Minnesota Vikings could target at the NFL combine in Indianapolis:

Positions of need: The story of the Vikings' offseason is their need to upgrade their offensive line, and their draft approach figures to be no different. They'll take a best-player-available approach, as many teams do, but positions of need can help dictate how they'll stack their board. Beyond the line, the Vikings could look for help at defensive tackle, where Sharrif Floyd’s injuries have been an ongoing issue. They might entertain the idea of adding a linebacker. And depending on what happens with Adrian Peterson, they might delve into a deep running back class to help with their 32nd-ranked ground game.

Five players the Vikings could focus on at the combine:

Zach Banner (tackle), USC: The Vikings could look at tackles like Wisconsin's Ryan Ramczyk or Alabama's Cam Robinson, too, but those players might be off the board by the time Minnesota makes its first pick in the second round of the draft. Absent a Rick Spielman trade back into the first round, a player like Banner could be more realistic for the Vikings. He certainly has the size for the position, at 6-foot-8 and 373 pounds, though he might be better as a Phil Loadholt-type road grader on the right side than he would be on the left.

Forrest Lamp (guard), Western Kentucky: Only 6-foot-4, Lamp is seen more as a guard than a tackle in the NFL, but he might be one of the best guards on the board, thanks to his nimble feet and strong work ethic. His frame might be too small for him to play tackle in the NFL -- you'll hear the dreaded arm-length question attached to his name -- but the Vikings could use help at guard after releasing Brandon Fusco, as well.

Antonio Garcia (tackle), Troy: He'll likely have to put on some mass to succeed in the NFL, after playing between 280 and 290 pounds in college, but he's a former high school basketball player with great footwork. He's not the type of player you'd expect to step in and protect Sam Bradford’s blind side on day one, but his combination of size (6-foot-6) and quickness will attract attention from teams that believe they can develop him into a solid NFL starter.

Alvin Kamara (running back), Tennessee: His stock is on the rise, and while he doesn't have breakaway speed, he's got good quickness and strength to pick up decent chunks of yardage. He also would be an asset in the passing game, which should become even more important as Pat Shurmur develops his offense in Minnesota. Kamara caught 40 passes for 392 yards and four touchdowns at Tennessee last year. In a deep running back class, he's one of the players who could make sense for the Vikings.

Jaleel Johnson (defensive tackle), Iowa: The 6-foot-4 Johnson attracted plenty of attention with an impressive showing at the Senior Bowl, and his first step will help him get an edge on blockers and penetrate into the backfield. He's probably not going to be a stout run defender in the NFL, but the Vikings could use help at 3-technique tackle, where they could release Floyd instead of keeping him on his fifth-year option. Tom Johnson will be 33 before the start of the season, and the addition of another interior rusher could make sense for a team that always seems to be on the lookout for players who can get after the quarterback.
