Cowboys attend workout of Wisconsin center

At the start of the draft process, the Cowboys were linked to Stanford guard David DeCastro.

But after spending $30 million to sign two free-agent offensive linemen, the Cowboys' attention shifted somewhat to defense in the eyes of draft experts.

Nobody really knows what the Cowboys are going to do with the 14th pick of the first round, but the team attended the private workout of Wisconsin center Peter Konz on Wednesday.

Konz didn't work out at UW's pro day, but the 6-foot-5, 314-pounder looked impressive, according to reports.

Guard Kevin Zeitler and lineman Josh Oglesby attended the private workout as well to get measured.

ESPN's Mel Kiper has Zeitler going to the Cowboys in the second round and Konz going to the Baltimore Ravens at No. 29 in his latest mock draft.
