For a fourth consecutive season, the Vikings will open with a different starting five on the offensive line.

The fifth starter will replace right guard Joe Berger, who retired this offseason. The new right guard could be on the roster, or already in the starting lineup. The Vikings' flexibility with last year's right tackle, Mike Remmers, means a guard or tackle could be in play when they pick at No. 30 in the NFL draft next week.

The Vikings have shown interest in top players at both positions, holding a private visit with Texas tackle Connor Williams earlier this month, a league source told the Star Tribune. They've also reportedly visited with Notre Dame tackle Mike McGlinchey, according to NFL Media.

Williams and McGlinchey are considered the draft's top tackles by NFL Media analyst Mike Mayock. The Vikings also have been linked to more interior O-linemen from a class dubbed among the "deeper" seen by Mayock.
