INDIANAPOLIS – Just because the Vikings offensive line exhibited a welcomed resurgence last season doesn't mean General Manager Rick Spielman has turned his attention elsewhere. The unit now faces a few questions, so line coach Tony Sparano and the Vikings' personnel department have been busy poking and prodding prospective linemen at the NFL scouting combine in Indianapolis.
"You have to always keep investing in that offensive and defensive line," Spielman said, "with the style we play, the philosophy coach [Mike] Zimmer wants to play."
Last season's improvement centered on the additions of free-agent left tackle Riley Reiff and rookie center Pat Elflein. The Vikings also signed Mike Remmers to play right tackle, but he finished the year playing guard in the final three games.
Whether the Vikings draft a tackle or guard — potentially with pick No. 30 — could determine what position Remmers plays in 2018, according to Zimmer. There might be an opening at right guard, with Joe Berger set to hit free agency, too.
"It gives us more options," Zimmer said. "If we find a tackle in the draft or if we find a guard in the draft," it could determine Remmers' position. It's worth noting Vikings coaches chose to play Rashod Hill over Remmers at right tackle in both playoff games.
The Vikings could again go the free-agent route — Dolphins right tackle Ja'Wuan James could be available — or turn to the draft's intriguing early-round options. Fortunately, this year's draft class is expected to bounce back from a 2017 group NFL draft analyst Mike Mayock called "the worst offensive line year ever."
"As far as interior, the top end of [2018] is really good," Mayock said. "Quenton Nelson will be gone early. The next group of guys: Isaiah Wynn, James Daniels, Will Hernandez, Billy Price, I think they'll all probably go, worst case, by the end of the second, beginning of the third [round]."
For possible guards, there's also Arkansas' Frank Ragnow.
