Query: Unfulfilled promise

The premise of the store is interesting. How did left tackle become one of the most important positions in football? The first half of the book does a fair job of walking through the reasons. (West Coast offense, LT, etc.)Unfortunately, at that point Lewis runs out of things to write about, so he starts talking about Michael Oher, an O Lineman at Ole Miss. Oher's story is intersting, but it is too early to tell. He is a "superstar" but only a sophomore. I also think that Lewis overdoes how great Oher already is.I also don't really understand what Oher's story really had to do with the original premise of the book. Is Lewis saying that because left tackles now make millions, Oher wants to be one? I would think that if Oher had come around in the 70s people would still have thought of him as a football player. Last time I checked lineman were big and strong (and quick) in that era too.
