Izzy has a regenerative condition on his hip I believe and had two surgeries in recent years. However, when healthy he is money. But coupled with his hip condition and his age, I think his stock may fall this year. I'd talk up those things to other people and then try to steal him late since he is very reliable when on the mound.
