We see this every year. Guy has tremendous 2nd half and everyone starts paying premium prices for him. Takes away any value he had because there is going to be regression but at the price he is going he can't. Lawrie was this guy last year and look what happened to him.
What I would think you would really want is a guy that shows his numbers weren't as good as they should have been. Not someone whose numbers are too good and not repeatable.
But heck if someone wants to take him, good for me. I will gladly take any of those other SP instead,
