I can't get on board with all the hate. Whether the positive was because he had no alternative for getting his knee back to the shape it needs to be for him to compete in MLB (30% IMO), because he truly ingested something by accident (10%) or some combination (i.e. he had to push the edge to get the knee ready but honestly thought he was on the good side of the edge (60%)), I think it's highly unlikely he was popping pills a la Conseco in order to be the strongest, most overpowering knuckleballer in the league. As for not telling the team, he must have thought that there was a reasonable chance that he'd win his appeal and it's certainly reasonable to assume that the advantage the team would garner from having that info 2 months earlier pales in comparison to the harm it might have done him should they have taken drastic action against him (i.e. what many of the lynch mob here have suggested).
Just think about what this guy is facing and what it means for his career before you try, convict and sentence him based on the limited info we all have. That goes for the domestic abuse as well. Unless there was some further news released that I'm not aware of what we know is that he prevented his wife from calling 911 during an argument, but both of them deny he ever struck or in any way harmed her. MLB thoroughly reviewed the case because of their efforts to take a hard stance on domestic violence issues and gave him the lightest sentence (15-games) of anyone since the current policy was instituted in 2015. The court case was retired and all charges dropped pending a 12-month probationary period which passed without incident. I'm not saying that he was definitely blameless or even that there's no chance that he's a PoS; I'm just saying that I'm amazed at how many people are convinced on the limited amount of public knowledge available that he's a wife-beater and should be vilified forever.
