I don't think I have ever played a starting pitcher into his 30s with a makeup below 70ish. How steep a decline is a guy likely to see, and when might it begin? The guy I am thinking of has already seen modest decline (one or two points) in his stamina and durability, but his other ratings are still solid. Also, he is an ace level starter, so even with regression, how bad could it get between age 30 and 35? Any examples or experience?
