The final mock drafts

Late Thursday night we'll know the entire first round of the NFL draft and begin the discussion of who did what and why.

ESPN's Mel Kiper Jr. and Todd McShay have their final mock drafts.

Kiper has the Cowboys taking North Carolina defensive tackle Sylvester Williams. Says Kiper:

The Cowboys currently have 31-year-old Jay Ratliff as one starting defensive tackle, and 30-year-old Jason Hatcher as the other. They may have other more pressing needs, but if the Cowboys can't put together a solid rotation on the interior of their defensive line, the conversion to a 4-3 is going to be ugly.

To get the rest of the first round, go here. You need to be an ESPN Insider to get the complete list.

McShay's final mock draft has Missouri defensive tackle Sheldon Richardson going in the first round to the Cowboys. McShay has Williams going to the Minnesota Vikings at No. 23.
