I'm not being ornery, merely expressing my opinion, just as you. In my opinion, you overstated how bad he was, particularly when you said his bust status was established in your mind prior to his injuries. It was a bad case of revisionist history.
Do I like watching him pitch? No he's frustrating as hell, so is Wakefield, but both, when healthy are effective, and in the end, no matter how ugly their path, I appreciate it when players are effective for the team. I say this realizing that advanced pitching statistics suggest Dice K is unlikely to find continued success if he pitches similarly upon his return. I agree with those stats, he needs to get better in his areas of deficiency. All that being said, the predictive value of those stats, and the frustration anyone feels while watching him, does not unmake what he did for this team in the past. He was a decent pitcher for this team one year, and a good one the next. Will that come back? Don't know, but it was what it was.
