I think there is an expectation, either from Coller or GR management, that being on the radio means acting like you are an authority, whether you are or not. 99% of the time things you say go in one ear and out the other anyway. You just want to sound like an authority when delivering that opinion. Rarely some a--hole, maybe even someone fitting my description, calls him out for, just an example, declaring Matt Cassel the Bills starter because he played just two series in preseason game #3, just like Ben Roethlisberger did. That earns you a block on Twitter.
