The Vikings know exactly who their two starting cornerbacks will be: second-year man Xavier Rhodes and free-agent signee Captain Munnerlyn.
Where things get interesting, though, is who will be the next corner on the field. Minnesota is bringing 10 cornerbacks to camp and they all have a variety of skills and attributes, which should make for a torrid competition among the other eight players.
When Minnesota goes to nickel and dime packages, which is likely on more than 50 percent of snaps, Munnerlyn will slide into the slot corner position. With his compact, muscular frame, Munnerlyn is a natural fit for the slot and will remind Vikings fans of Antoine Winfield's stellar play at the position.
On paper, it would seem the most likely candidate to be the third corner is Derek Cox, the five-year veteran the Vikings signed to a free-agent deal in March after he was waived by the San Diego Chargers.
Cox had three total four-interception seasons while with the Jacksonville Jaguars and was signed to a mammoth deal by the Chargers before the 2013 season. But he was a huge disappointment in San Diego.
At 6'1" and 195 pounds, Cox has good size and has proved he has good ball skills during his career. Just as we said at safety, the Vikings are looking for players who can make plays on the ball and generate turnovers. If Cox can shake off last season, he could be a free-agent steal for Minnesota.
Josh Robinson will try to live up to the promise he showed early in his rookie season in 2012 when he had two interceptions. Robinson is one of the fastest players on the Vikings roster, but he'll have to put the 2013 season behind him when he failed miserably trying to play the slot corner.
The Vikings have two 2014 draft picks, who should both compete for roster spots. Kendall James, a sixth-round pick out of Maine, and Jabari Price, a seventh-rounder out of North Carolina, both have enough upside to stick.
James might be the best athlete the Vikings have at the position, but at just 180 pounds, he'll have to prove he can handle the physical demands of the NFL.
Price is a rough-around-the-edges prospect, who can hit and play the ball in the air. One would think that either of these two could land on the practice squad if they don't make the active roster.
At 5'10" and 175 pounds, Marcus Sherels probably has no right to be an NFL player. He's an undersized punt returner who lacks ideal speed. He's been on the "probably going to be cut" list during every one of his four seasons in the league.
All of which only highlights what a phenomenal season Sherels had in 2013, setting a Vikings record with a punt-return average of 15.2 yards.
Sherels has shown marked improvement every year in the league, both as a returner and as a corner, and it would be a complete surprise if he didn't make the final roster.
That leaves Shaun Prater, Julian Posey and Robert Steeples as the long shots to make the team.
However, as anyone who's watched Minnesota over the last five years knows, this is a team that's starved for interceptions. Any player who can make plays against the pass in training camp will have a shot at making the team.
