I see it as two different issues stemming from the same event. Taking things one by one....
Machado proved he's a cheap shot artist with his "slide". It was after that when the s*** really hit the fan.
Issue #1 - Machado didn't show any contrition... no apology, no nothing. He didn't even fake it!! That's inexcusable. IMHO there's no way anyone can have his back after that.
Issue #2 - After Pedey's team stood up for him Pedey then threw his teammates under the bus with, "It's not me, it's them". Again, inexcusable. He had the option of saying 'something' or saying 'nothing' and 'nothing' would have been a much better choice. As Larry Lucchino has been quoted as saying, "Nothing is sometimes a good thing to do and always a good thing to say."
I'm not quite as down on Pedey as I am on Machado - maybe because he was the victim in the original event and maybe because he plays for the Sox - but the whole thing tarnished my image of him. Pedey had the right to remain silent but didn't have the ability. When your whole team stands up for you, you don't undercut them.
