The ongoing left tackle question

The Panthers made a questionable trade for Russell Okung, hoping to end their string of troubles at a critical position. Okung’s flirting with opting-out and a potential early retirement can’t make the front office feel easy, though. Their best backup at left tackle is Greg Little, who missed 12 games as a rookie due to his own injury problems, including concussion issues. Carolina needs Okung to hit the ground running in these padded practices and stay healthy the whole year, or else dealing Trai Turner could turn into a total loss.
