If you’ve read Michael Lewis’s book “The Blind Side,” or have seen the Academy Award-winning movie based on the book, you know about Michael Oher, the virtually-homeless Memphis teenager, who went on to become a college All-American football star and first-round draft pick by the NFL’s Baltimore Ravens.

I met and interviewed him in 2011.

In his book “I Beat the Odds” Oher fills in his backstory — the crack-addicted mother, the nearly-dozen brothers and sisters who often had to fend for themselves, the feared social workers who he now realizes were often reduced to tears in their efforts to help him and his family.

But there’s a whole lot more you don’t know about Michael Oher — and some of what you think you know may be wrong.
