One of the major tenants of that code is keeping a low profile. Typically, offensive linemen don't want to be seen as individuals. They want to be identified as a unit.
That's what made things difficult for offensive tackle Michael Oher after the movie "The Blindside" became a national hit in theaters.
Oher became a star. He was in the spotlight. That movie has been attached to him ever since, and a lot of good came from people learning his rags-to-riches story.
"It's helped and inspired so many people across the world," Oher said.
