Point taken (points, actually
). Trading based on an injury that might or might not happen does not make sense, especially when you're talking about one of the league's premiere players. I don't really see him as struggling, either - both his numbers and the way he's handled himself on the mound seem fine to me.
Still, it's understandable that Unit owners are getting a tad nervous about his tremendous workload, especially those who follow stress factors or one of the many variations thereof. Johnson is at the very top of most of these stress lists, and that, while it obviously doesn't mean he's going to break down, isn't exactly where you want to see your ace. I admit that the Unit's pitch counts have taken me a bit by surprise - especially with all the talk that the D-Backs want to make absolutely sure he'll be in top shape come playoff time.
Aside: What does everyone think of these stress ratings? They're certainly en vogue in the fantasy community this season. Are they useful? Long-term or short-term? Or are they just a weak attempt to predict the unpredictable?
