I can't grant forgiveness because I'm not looking for contrition. None of this is personal, at least not for me, it isn't.
So I think we can agree that Morton has not been horrible, as you said. I can get with "mediocre", provided you don't mean he's been below average, because he has not. He's been slightly above average overall in the things he can control. He's doing what we want him to.
The bigger problem in your apparent worldview might be that you think he's been not good, yet you would peg him as our #2 starter for the playoffs, which suggests to me you might believe we're going to get smoked off the field for lack of starting pitching. We might anyway, but I don't see our starting pitching prospects for October as being as dire as all that.
