Re: What went wrong with Todd Coffey?
2 things I have noticed:
1. .357 BAPIP
2. HR/FB going from 10.4% to 27.5%
When dealing with small samples, luck can play a major factor. I'm not suggesting that all of Coffey's struggles have arisen from poor luck, but I think it's a major factor. Those 2 things are unsustainable and not due entirely from poor pitching. With more innings, I would bet that both those rates would come storming down towards league average rates like it basically always does, and Coffey returned closer to his 2006 numbers.
Now there is some thought that players who get plenty of groundballs (like Coffey) should have higher HR/FB rates, but even then his current rate is still completely out of whack. There should only be a more minor disadvantage for Coffey in that area.
