Skubal is one pretty big piece to lose! When all the great prospects are ready in a couple of years, it might be time for Greene, Torkelson and Carpenter to leave. I don't think there is some magical point in the future where we can say they are ready. They are ready now, maybe as much as they'll ever be.
I am not saying this in response to their 1-9 funk. If I thought they were a bad team, I wouldn't suggest they explore a big move. I don't have a particular move in mind. I wouldn't want them to trade top prospects for a two month rental. If there is someone signed past this year, I'd consider it.
