In my replay starting in 1969, Willie Mays was a 2 in center field for 1969 and 1970. I traded him after the 1970 season mostly because of his shoddy defense.
I recently played against his new team in 1971 and now he's a 10 in CF.

Did they change because of what Mays did in real life, or because I played him there almost the entire 1970 season?

And, when in the offseason do those new numbers show up?

I may not have traded him if I had noticed he had improved that much.
