BOSTON -- Five years ago, San Francisco 49ers fans weary of losing might have cringed seeing team executive Paraag Marathe representing them on a "Revenge of the Nerds" panel put on by Massachusetts Institute of Technology.Marathe himself might have cringed. At the time, the academic credentials Marathe brought to the NFL made him an outsider in an acutely insular world. He was conveniently cast as a "non-football guy" distracting the 49ers from the important stuff.
