Extra Crispy redux

I decided that it was important to go over two major issues of the Sanders talk:

1. There are too many sources confirming the A's interest in Sanders for it not to be true. So it is a given that there is some interest in acquiring him.

2. Sanders has played in the NL his entire career; while this may seem trivial with the invention of interleague play, let's look at some players who played at least 5 years in one league before switching to another:

As you can tell, not many players were able to avoid an adjustment period durring the first month of playing in the new league. I hope to get some more players to futher the sample size but I would venture to say that most often than not, players who switch leagues have to go through some adjustment. The question is, if a player is currently having a sub-par season, how much higher is the adjustment curve?
