Would be interesting to see how that compares with WAR.
So at age 29, Willy will play his "peak" age season this year. At ages 24-26 were his best years (126, 121, 110 OPS+; 1.9, 4.2, 4.0 WAR). Obviously age 24 was limited ABs reducing his WAR and age 26 was heavier on defense). The last two years have been decent, but lower: 94, 118 OPS+, 3.0, 3.1 WAR.
So do we really think he can get back to being a 4.0 WAR player? Or 120+ OPS+?
This started with the comment of "his best days are behind him". I would say that is still true. Maybe he hits 3 WAR again and probably 2+ WAR regularly. But I can't see another 4 WAR season coming from him.
