I'm not a big fan of the WWL but their Grantland editorials are one of the few things I read regularly. He is being suspended for calling Goodell a 'liar' on a podcast. I guess he didn't meet ESPN's beliefs of attaining inter-stellar sporting news domination.
Here's a snippet:
Simmons' podcast was released Tuesday. He called Goodell a "liar" about not knowing what was on a security video that showed former Ravens running back Ray Rice hitting his then-fiancee in an Atlantic City elevator. Simmons also challenged ESPN management about his right to call Goodell a "liar" on the podcast.
