Although I am not sure if you are taking exception to the way Fred has criticized Ace or if it is more about criticizing him in the first place, it is not one appearance.
In the first place Ace's reputation is to put in a good year to year and a half and then turn into a royal pain in the ass who carries his s*** with him everywhere including the mound. That is what he did in NY and it looks like the same pattern here. He is a card carrying dick-head, a few sandwiches short of a full picnic.
In the second place at the end of last year he completely gave up. If you watched how he pitched at the end of last year, that is what giving up and giving in looks like for a pitcher. He just threw in the towel and rolled meatball after meatball right down main street as if straight as an arrow FB's regardless of their velo were going to beat anybody. They promptly got deposited, as they should have. So I no longer buy the tough guy argument. He is as tough as the school yard bully that just needs to get whacked across the mouth to cave.
2011 was part of the grace period Ace usually allows you before he hits you with the real Ace. The shame if it is that if he could kept his head screwed on straight and did not carry his ******** out onto the mound with him, he would likely be a valuable asset for somebody for more than one season at a time.
