Dallas Cowboys owner Jerry Jones is impressed with rookie defensive end Randy Gregory. “It’s easy to see his talent, very easy to see,” Jones said.“His willingness to take coaching from his teammates, as well as the coaches themselves – all of those things, you like. Those are intangibles.” Jones has seen weight gain from Gregory who was 6-foot-5, 235 pounds at the NFL scouting combine. “I’m pleased that he’s gained the weight he’s gained,” Jones said. “I’m going to round this off, but I’d say he’s up 15 pounds. And he doesn’t labor in any way with that 15 pounds. He can lose it — I’m envious — he can lose it as fast as anybody that you can imagine, but he can also put it on. His diet – he’s doing some good stuff. He’s been very responsible.” Follow me on Twitter: @RavensInsider Aaron Wilson covers the Ravens for The Baltimore Sun
