Richard Sherman and Jonathan Martin both went to Stanford and played together there in 2009, 2010. This part of their backgrounds is a shared trait, but for the most part they grew up very differently. Sherman overcame the more traditional inner-city challenges to develop his skill-sets. Martin was born into a family of middle-class and more upward-mobile wealth.
What is mostly similar of Sherman and Martin is how they are dispelling the stereotypes of black athletes.
