@Region Philbis,
Far too much legal BS and big time money is at stake. If MLB announced all the candidates that they had the goods (provable), you could collapse the pennant races. I think just about every contender has one or more top performer who are using PED or have recently done so in their past.
Here's my burning question: Why was Braun first?
IMHO, it's no small coincidence that a major player like Braun is on a non-contending team that they offer HIM up as a sacrificial lamb. It also doesn't hurt that he pissed off MLB last year with squirming out of the prior legal case on that chain-of-custody technicality.
