I only watch ESPN when games are on.
On my morning commute (about an hour), I split my listening between three shows: Local morning show (half music/half talk - I only want talk in the mornings); Free Beer and Hot Wings; and ESPN Radio (Mike/Mike, Golic/Wingo, now Keyshwan, JWill and Max Kellerman).
I start with whichever station isn't on a commercial break/playing music. Then I switch the station every time a commercial or song comes on.
As far as the ESPN morning shows go, Mike/Mike was the best of what's been offered. I actually like Keyshawn Johnson. I think he's smart and he's funny - and I enjoy his commentary. Jason Williams, I could take or leave. Zubin worked about one day a month. I've never been a Max Kellerman fan and that hasn't changed since he joined the show. He spends too much time plugging his other ESPN shows/appearances and bragging about his past appearances.
I was never - and still am not - a big Mike Greenberg fan, but Mike/Mike was so much better than anything that has followed it.
