Even if it turns out that Kromer was just a complete dick, kids were average sized teenagers whose only crime was sitting in an occupied chair, and Kroner just decked him because it seemed like fun (in which case I might support giving him some jail time), why would you fire him?
Does this reflect that substantially on his coaching ability? I get the PR aspect, but is anyone honestly going to boycott the Bills because they have a position coach who's an !@#$?
Unless they think replacing him = more wins I think it would be !@#$ing stupid to do so.
