A year ago, Cedric Ogbuehi had good reason to think that he would be signing a contract in the neighborhood of $20 million — the result of being a top-five N.F.L. draft pick.
Entering his senior year at Texas A&M, Ogbuehi was set to move from right tackle to left tackle, a position so vital that there is a best-selling book and hit movie about it called “The Blind Side.” The Aggies’ starting left tackle in 2012 was drafted second over all and signed a contract guaranteeing $21.2 million over four years. Their starting left tackle in 2013 was drafted sixth over all and signed for $16.
