Is he going to be able to have his velo and spin rates for 600-800 innings or just a 10 inning stretch when the adrenaline is pumping for a WS? If he pitches great for six months to start this year and them blows his arm out again for a 3rd time, it's not a success story.
He needs to come back and pitch well for a few years at least for it to be considered full performance.
