ESPN 1500 Twin Cities reports the Vikings are concerned about Josh Robinson's transition to nickel cornerback.
Robinson is set to replace Antoine Winfield in the slot this season, but has struggled early in camp and profiles as a liability against the run. "Josh has never been inside before, so it's a big transition," DC Alan Williams said."He's going to make mistakes." Even if Robinson continues to struggle, he's likely locked into the nickel job. With Jacob Lacey as his only competition, the Vikings don't have any other viable options.
