Selected sixth overall in 2012, Claiborne has two interceptions in two seasons and missed six games last year with recurring hamstring injuries. With the offseason over, Claiborne believes 2014 will be different.
"I'm ready," Claiborne said. "Hands down, point blank, I'm ready. I feel better than I've ever felt in a long time. I'm just anxious for you guys to start asking me something else: What about the interception you made? I'm ready for those type questions."
Expectations were raised ever since the Cowboys traded up to get him and immediately said he was the highest-graded defensive back they have had since Deion Sanders. The production on the field has not matched it. He lost his job to Orlando Scandrick last season and there is no guarantee he can win it back.
But defensive backs coach Jerome Henderson has noticed a different Claiborne.
"Competing his butt off," Henderson said. "He's embraced that he's got to play better, and he's doing a good job."
Coach Jason Garrett has noticed a different Claiborne physically. He has not added weight, but Garrett believes Claiborne is stronger. He has had to rehab from shoulder and finger surgeries this offseason.
"He's more mature physically, and I think his technique is getting better," Garrett said. "I think with that, you develop some confidence, and you need confidence in any position you play, but you certainly need it if you play corner in the NFL. You're out there by yourself a lot."
With five weeks to go before the Cowboys head to California for training camp, Claiborne has a couple of weekend trips scheduled but he plans on working out through the summer.
"I just don't want to lose nothing that I have now," he said. "We have a lot of time before we actually get to camp and all but there's things that I built right now. I felt like I put so much into this offseason and I invested so much. I don't want to lose that. I'm still going to be on my grind like it's still the (organized team activities) or we're about to report next week."
It has not been perfect, but it has been better for Claiborne. He allowed Dez Bryant to sneak in for a touchdown Wednesday but later broke up a back-shoulder throw in the end zone to Devin Street. He has found himself going against Bryant daily in practice. When they weren't matched up, he pulled a younger cornerback from the field in order to be matched up against Bryant.
"Me and him talked about it before we even started up that we want to be the best and we want to go against each other," Claiborne said. "We feel like we both compete at a high level. I get good work when I go against him and it's vice versa. When I'm not up there, he's telling me to come. We're trying to help each other so we can be the best for our team."
