As I said in the game thread, I think Dickerson is a terrific 3rd base coach. Just because he doesn't have a perfect record doesn't mean he's not a great coach. He's very aggressive and it's lead to a lot of runs that most fans don't think about because the ball is way up the line or cut off without a play. Some coaches would have held the runners in those situations, Dickerson sent them to stay aggressive.
I remember some really disappointing 3rd base coaches from the past. We're lucky to have Dickerson.
