Mel Kiper sees Kenny Vaccaro slipping to Cowboys

In a conference call with reporters, ESPN NFL Draft expert Mel Kiper Jr. dismissed the notion that guards Chance Warmack and Jonathan Cooper will be around when the Cowboys select at No. 18.

Safety Kenny Vaccaro, who is projected to be the first safety taken, is falling in Kiper's eyes.

"To see them drop all the way down to 18, if they don't, Vaccaro could be there," Kiper said. "Vaccaro has slipped down, I think into the 20s, but he would be a possibility. I bet Sylvester Williams from North Carolina, you need a defensive tackle to fit that Monte Kiffin scheme. Then you look at the second-round possibilities, a Justin Pugh."

Kiper said the Cowboys need to upgrade the interior of the offensive line and believes Warmack and Cooper are "all going very high."

So to improve the interior, Kiper offers Pugh, from Syracuse, "who's a left tackle, can be a guard, can be a center. They have to improve the interior of the offensive line, Dallas does, and Pugh would be a very nice addition at that point."
