I kinda like Walter's current first four rounds for Dallas (dated 1/5/2012):
1.
Dallas Cowboys: David DeCastro, G, Stanford 
The Cowboys have major issues on the interior of their offensive line. Left guard Derrick Dockery is a free agent after missing most of 2011 with a knee injury. Center Phil Costa sucks. Right guard Montrae Holland, meanwhile, can't really be relied upon.
David DeCastro is one of the top interior linemen prospects to come along in years, and he's the highest-ranked prospect on the board. This is a perfect match.
2.
Dallas Cowboys: Stephon Gilmore, CB, South Carolina 
Many mocked Prince Amukamara to the Cowboys this past April for good reason. If you didn't see the Sunday night game against the Giants, Hakeem Nicks and Victor Cruz ran down the field with ease against a putrid secondary. Orlando Scandrick isn't very good, while Terence Newman has just collapsed following a hot start.
3.
Dallas Cowboys: Kendall Reyes, DE/DT, Connecticut 
The Cowboys had the option of picking J.J. Watt at No. 9 overall in the 2011 NFL Draft. They went with Tyron Smith, who was great in his rookie campaign, but they were hurting at the defensive end position as a consequence.
4.
Dallas Cowboys: Donte Paige-Moss, DE/OLB, North Carolina 
Donte Paige-Moss is a giant ******, but Jerry Jones has taken chances on headcases before. Besides, Anthony Spencer has been hot and cold this year. He'll be a free agent in March. I doubt Dallas will want to pay him the money he's looking for.
