Here was my best example of picking up a "used" FA...
Mike Schmidt on his 80 card...

The team that was using him was playing in County Std. It seemed like he had hit a lot of HR in only 68ABs playing in that STD and I was playing in Ful Co. That is one stat I look at is how is a power hitter doing in say a "non-friendly" std. I will also look at triples, BA splits, K/IP ratio. I think many times that mgrs draft a guy thinking he will perform no matter what in their std and it turns out to not be a good fit.
