Livo is doing fine.
I don't know what you were expecting though. A lot of these guys are older, on the downside of their career, or in the case of a guy like Lannan... severely limited by a lack of talent. It can't be that much of a shock to you.
It's not shocking to me but others were claiming that our rotation was elite and was pitching to their normal levels.
Marquis, Lannan, and Gorzelanny are not good pitchers.
Livo has been okay like you mentioned but not elite.
JZ has been good but too many mistakes.
We need an infusion of more talented arms that have potential to be more than #5 starter
