Reading about the case it was a joke that shouldn't have ever been. The flip side is I doubt we're going to see any Fed investigations on steroids in professional sports for a looong time.
It may have been more for all I know. I do know they have spent ridiculous amounts of money chasing Clemens and several others. I thought it was 2-3 mil just for the Clemens case.
Whatever the amount, they made their point a long time ago and they can stop the witch hunt now IMO.
