Having him actually participate in camp and the preseason helps - he has had a lot of pre-camp and camp injuries in his past, and it has robbed him of valuable conditioning and reps.
Where I worry with Claiborne is when he encounters adversity. He has not proven to be strong willed and strong minded in his career to this point. I would like to see how he bounces back if he has a game similar to the Ram game in 2014, when he made Brian Quick look like Mike Quick.
That being said, he looks much improved, much stronger and more confident in playing zone concepts, which has been a struggle for him. Hope he can keep it up - it would be huge for the Cowboys if he does.
