Let's throw another pitcher in here, one who no one is going to argue is or likely will be injured: Matt Harvey.
The Mets have eased him out with more days between starts and plan to shut him down after a few more starts. Why? Because he is near/over the most innings he has pitched in his professional career and has looked much less effective in his last four or so starts.
Is that a bad decision?
Ridiculousness across all sports:
(1) "You have no valid opinion because you never played the game."
(2) "Stats are irrelevant. This guy just doesn't know how to win."
