I was just looking at Blake's numbers and it's weird to me that he has a negative dWAR. He's made no errors and has gotten to every ball that wasn't "impossible."

If there was still a residual effect from that, we'd be seeing it right now. He's with the team day in and day out. He's a fixture in the dugout. If he was a rotten apple, the barrel would've been spoiled this year.
