My first post was a little harsh on him. His early Page 2 mailbags were fantastic and as someone mentioned his live blog of the opening weekend of the NCAA tournament with his best friend was gold, but he never really offered a lot more than than light-hearted sports writing.
But as his role on ESPN expanded I never felt like he added value anywhere that he showed up. He never had interesting observations when brought on live TV and he wasn't very entertaining to watch on the air (usually you need to be one of the two to survive). As a writer, his staple articles seemed to get stale -- I'm not sure anyone really cares if Thabo Sefolosha has the 89th worst contract in the NBA -- and he never had great insights into sports. Yes, he can put together 3,000 words weaving together SNL, the Mayweather/Pacquiao fight, and the NBA play-offs, but it'll include played out jokes and questions from readers that are just trying too hard to be funny. The articles never really include any original insight to the games.
I'll admit, I don't listen to his podcasts, which have been his big focus the past few years.
On the other hand though, the idea to start the 30 for 30 series is the best thing ESPN has done in the past decade. I don't think he's actually done a feature, but he does deserve the credit for bringing that to the table.
