OL would be a waste. McKinney is a beast and Loadholt will probably be a good OT for a decade. Add that to Sullivan and Hutchinson, and Minnesota has a good OL (health providing) for the next few years.
One thing I think my happen, and would be good for replenishment is getting Liuget, the DT out of Illinois. He is a wide body that could develop under Pat Williams. A lot of good GM’s draft studs when they currently have them (GB with Rodgers, Colts with every WR they draft).
McKinney is terrible. He was the main reason Favre had so much trouble last year -- he simply could not trust the man guarding his blind spot. Hutchinson was hurt most of the year, as was Sullivan, so those positions were held down by backups. Loadholt shows great promise but took a significant step backward last year. They need line help and will need a new left tackle sooner rather than later. Naturally, though, the buzz is that they will go d-line, which would be the worst pick they could make other than a running back.
