The Cowboys will be looking to improve in the interior of their offensive line. Offensive line coach Bill Callahan will help, but Dallas could use better players.
Center Phil Costa was the 30th-best center in the NFL, according to Pro Football Focus. Right guard Kyle Kosier, 33, didn't have his best season. He tied for 46th among guards, according to the Web site. The Cowboys started three left guards. Montrae Holland played there for 10 games after being re-signed when rookie Bill Nagy was lost for the season. Pro Football Focus had Holland tied for 16th among guards.
Stanford offensive guard David DeCastro could be available at No. 14 in the draft, but signing a free agent is a possibility, too.
The best guards slated to become free agents are New Orleans' Carl Nicks and Baltimore's Ben Grubbs. Houston's Chris Myers, Green Bay's Scott Wells and San Diego's Nick Hardwick are the top centers whose contracts expire.
Nicks was named to the All-Pro team, and Pro Football Focus said he had the second-best season behind Philadelphia's Evan Mathis by allowing two sacks, two quarterback hits and eight pressures. The Saints are expected to do all they can to keep Nicks.
But he is expected to command more than his teammate, Jahri Evans, who signed the richest contract ever for a guard last offseason. Evans signed a seven-year, $56.7 million contract, with $19 million in the first year and $25.7 million over the first three years. The Saints could franchise Nicks, who turns 27 in May. However, that would entail getting quarterback Drew Brees under contract first. They also have receiver Marques Colston set to become a free agent.
Grubbs was 12th among guards, according to PFF. He allowed four sacks, two quarterback hits and six pressures. Baltimore was 10th in rushing. Grubbs turns 28 in March.
Myers had the best season of any center, according to PFF. He played 1,060 snaps and gave up one sack. He also was a big reason the Texans ranked second in rushing. He turns 31 in September.
Wells was the fourth-best center, and Hardwick was 12th. Both would be upgrades over Costa. Wells just turned 31. Hardwick turns 31 in September.
