CHARLOTTE – By this point, left tackle Michael Oher has put his 2014 season in Tennessee well behind him.

He quickly assimilated in Carolina and is coming off arguably his best performance in last Sunday's 37-29 victory over the Green Bay Packers, who didn't record a single sack.

But with a trip to Nashville looming for the unbeaten Panthers, Oher's matchup against his former team is an obvious storyline.

Unsurprisingly, he doesn't have much to say about it.

As for why his Tennessee tenure lasted just one year: "I have no clue," said Oher, who alluded to some philosophical differences when he first arrived in Carolina. "I just wasn't the guy for the job, I guess. It just doesn't work out sometimes."

Oher said he's the same person, same player he was with the Titans. He is healthier, however, after struggling with a toe injury in 2014.

"I come to work every day and I try to be there for my team," Oher said. "That's all I've been doing my entire career."

Oher has been a perfect fit at left tackle in Carolina. The first word out of head coach Ron Rivera's mouth when asked what Oher has brought was "stability."

"He's played very well for us at the left tackle position," Rivera said. "He's done the things that we've asked him to do. There's a toughness about him that helps permeate throughout the rest of the guys as well."

Another layer to this storyline is the fact that Byron Bell, the man Oher replaced at left tackle, is now the starting right tackle for the Titans.

Bell was moved to left tackle in Carolina following Jordan Gross' retirement at the conclusion of the 2013 season. It was a challenging transition for someone who had played right tackle the previous three seasons.

"I just remember how solid a football player he was for us," Rivera said. "He did the best he could. We put him in a tough position. Right tackle is probably is more natural position for him. But he was athletic enough and he was willing to try it at left tackle for us."
