The Vikings looked to the Big 10 (or 11 or 12 or however many teams they have now) for their 4th round selection, taking DT Christian Ballard out of Iowa.
The scouting report on Ballard is straight-forward: he has great talent but is still raw. Right now it looks like Ballard could develop into either an end or a tackle. Also – and this may end up meaning nothing, as we learned with Percy Harvin – Ballard flunked a drug test at the combine. This failed test is probably why Ballard was still available in the 4th.
With Ray Edwards likely leaving, Pat Williams almost certainly moving on and Kevin Williams free to be suspended for 4 games after the end of the StarCaps mess, the Vikings clearly needed to beef up their defensive line corps. This they have done with Ballard.
