I have a hypothetical question. Feel free to explain it to me as if I were a child.
Let’s just say we’d had a really bad shortstop who played every game this season with only a -1.1 WAR, and through magic we were able to replace him with, say, Alan Trammell with a +6.0 WAR who likewise played every game in Ripkenesque fashion.
I am assuming it’s more complicated than just replacing Trammell’s figures for the profoundly subpar player and coming up with a +4.9 WAR.
But what would it look like? How much better would the team be?
