Overrated writer?
Probably the entire Dead-spin crew. Granted some of their work is downright fantastic, but there seems to be an opinion of many people that they can do no wrong and are always right. Furthermore, people seem to think that in some sense, they 'take the high road' compared to other sports writers. But, they are the same guys that act with the same childish and unprofessional behavior when they don't get their way. When they get snubbed by an athlete or another sports writer, they hold a grudge until they get their way.
I can stomach Dead-spin over most everything else, but that's not setting the bar that high.
Analyst?
Ron Jaworski.
He's become a joke and is now more style over substance. He's become fully ESPN-ized and has become a caricature of himself and it's hard to take him seriously with so many asinine opinions and questionable analysis. He now relies on his early days at ESPN where he struggled to get TV time, but was an excellent analyst; to help his reputation.
Announcer?
Johnny Miller.
He's horrendous. If you know anything about golf and the golf swing, he essentially is speaking gibberish out there, 90% of the time.
