I like Chris Fowler's enthusiasm for tennis and its' personalities. He's relatively new to the sport. He really took to tennis after he became a moderator at majors. His 'jock boy' angle on tennis happenings is different and interesting. The guy before him (Traybert??) didn't bring much to the table.
I'm comfortable with the group of commentators at ESPN2 for this major. They're doing their jobs and they don't bother me enough to interrupt my enjoyment of the tennis.
I want to add to the other voices who enjoy Darren's insightful commentary. He's smart and likeable.
On the Williams commentary from all of the talking heads. The Williams sisters are good press. At any time in tennis they're the best thing that ever happened to the game or the worst. Right now they're the only US women of note so they're great!
