Can you imagine this boards reaction to a AAA hitter that put up wRC+ of 104 and 94 his first to years in AAA and a wRC+ of 31 and 90 and handing him the 3B job?
Or a AA pitcher with 19.3% K% and 13.1% BB% that on promotion to AAA improves that to 21.8% and 10.9%? For people that don't follow those numbers they are bad.
