I'm guessing that as Dickey gets healthy and the weather warms up, he'll be a lot closer to his average performance level of the past 3 years. He's been injured essentially all season but didn't want to go on the DL because of the injury issues in the rest of the rotation. He's also talked about the cold weather making it harder to throw a knuckleball. The data reflects that. His BB% since his breakout with the Mets in 2010 breaks down as follows: 9.4 BB% in April, 7.3 BB% in May, 6.0 BB% in June, 5.3 BB% in July, 4.8 BB% in August, 6.2BB% in September. All 6 months have a sample size of over 400 Batters Faced and the threshold for BB% stabilization is 170 Batters Faced. Obviously as a knuckleballer he is highly reliant on control of that pitch. If he can't throw strikes with it, he's going to give out more free passes and be forced to throw more fastballs. His ERA follows a very similar trend to his BB% for those months. Buy low window is closing... would be a good idea to see if you can catch somebody trying to sell high off of one hot start.
