NFL Mock Draft 2013: Cowboys select Sheldon Richardson at No. 18

The Dallas Cowboys just missed out on the playoffs in 2012, falling short against the Redskins in Week 17. While there was plenty of disappointment in Dallas, the coaching staff and front office know their team is just a few pieces away from really competing in the loaded NFC East.

Armed with the 18th overall pick at the 2013 NFL Draft, the Cowboys are likely going to improve their offensive or defensive line. Few defensive tackles in this year's class are as physically gifted or talented as Sheldon Richardson is. Here is Josh Norris of Roto World with the latest on Dallas' projected pick.

18. Dallas Cowboys -- DT Sheldon Richardson, Missouri

Richardson's talent likely exceeds this slot, but if he is on the board the Cowboys have found their 3 technique defensive tackle. The Missouri product has some Fletcher Cox to him and can be scheme versatile. Richardson ended his career with the Tigers on rocky terms, but he has plenty of talent.

As Norris made reference to, the only question with Richardson is his ability to be a good teammate both on and off the field. His recruitment out of high school was a mess, and after spending some time at a junior college, Richardson butted heads with the coaching staff at Missouri. He was suspended for a crucial late-season game that had bowl game implications, too.

If Richardson is able to get his act together, he could be a steal at No. 18 for the Cowboys. All of the physical tools are there. At 6'4 and 295 pounds, the All-SEC 2nd Team selection would clog up the middle and provide Dallas with another solid pass rusher.

In a different mock draft from SB Nation, the Cowboys selected North Carolina guard Jonathan Cooper.
