The Minnesota Vikings were never more determined to fix their blocking problems than were this spring, after a 14-win season was ultimately torpedoed by too much interior pressure.
Donovan Jackson became the final piece of the upgrade.
The Vikings made the Ohio State guard the 24th selection in the NFL draft on Thursday night, completing an offseason overhaul of the interior of their offensive line after ignoring an opportunity to trade down and add to their small number of picks.
The 6-foot-4, 315-pound Jackson, who was the third guard taken behind Alabama's Tyler Booker at No. 12 and North Dakota State's Gray Zabel at No. 18, was a second-team Associated Press All-American for the national champion Buckeyes.
''He's got size. He's got length. He's got power,'' Vikings coach Kevin O'Connell said. ''A lot of things that we're very excited about.''
Jackson was a three-year starter at left guard who moved to left tackle midway through his senior season after an injury at that position, even though the switch posed a potential risk to his draft stock.
''I just wanted to win," said Jackson, who allowed only five sacks in 1,293 pass blocking snaps in his college career, according to Pro Football Focus analysis.
After struggling for several years to stabilize their offensive line, the Vikings finally got aggressive and signed center Ryan Kelly and right guard Will Fries in free agency — both away from Indianapolis — for a combined, guaranteed total of more than $53 million.
