Jan 30 9:54AM CT By Calvin Watkins Today is the Senior Bowl and if you're watching here's a few players to check out as far as the Cowboys are concerned: The Cowboys are interested in drafting a running back, either because they will cut/trade Marion Barber or trade Tashard Choice. I would keep Choice and just cut Barber, but that's me. As for the Cowboys expect running back Ben Tate, a 5-foot-11 218 pounder from Auburn to give them some interest. Virginia cornerback Chris Cook is an interesting prospect. The Cowboys interviewed Cook at the Senior Bowl and asked could he play free safety. Cook said yes, though he played mainly both corner spots at Virginia. The Cowboys, while somewhat happy with Patrick Crayton on punt returns and Felix Jones on kick returns, are looking for more speed on punt returns and someone who can make a impact on kick returns in this year's draft. Cook has returned kicks before, but he won't in the Senior Bowl. Don't be surprised if the Cowboys draft a wide receiver. They've talked to quite a few. Clemson's Jacoby Ford is one to watch out for. On Wednesday, Ford said he spoke to the Jets, Packers, Bears, Browns, Colts, Vikings and Buccaneers. He did not talk to the Cowboys, but that doesn't mean they're not interested. Ford said he needs to improve against press coverage but once he gets in open space he's gone. Ford was asked what does the think he can run at the combine, "I can guarantee a 4.2. Running is second nature for me." Ford's best 40 time, according to him, was at prep school when he ran a 4.12. Ford said he weighed 163 pounds at that time. Now, he's at 181. Watch the offensive linemen today. Idaho's Mike Iupati, Baylor's J.D. Walton, Arkansas' Mitch Petrus and N.C. State's Ted Larsen have a chance to help themselves. The Cowboys scouts feel Iupati will be gone by the time they draft late in the first round, but it's worth watching everybody else.
