I found it really suprising when I saw that he playbyplay commentates the arena tournaments for blizzard. I saw him at one broadcasted trounament and he seemed a bit overwhelmed. Which understandibly you have 10 people nuking and healing all at once. But at the blizzcon tournament he did an awesome job. Even after the matches explaining why this or that helped a team win. I was pretty impressed for a man who's claim to fame is foobaring the rookery up lol.
The most stressful, yet provides the most gratification..
