The reason why baseball is cracking down on roids is 2-folded. One, the players who do not juice are speaking up (finally). The MLB has a legit concern over younger players and prospects juicing at a younger age. Not only does this give them an inaccurate assessment of their prospects but it also puts a lot of pressure on them from anti-juicing groups. Where will this end if MLB stands around and does nothing? Already, there are players in HS who have died juicing up in hopes of striking gold in the MLB. It just doesn't give the MLB the type of positive pub that they want/need right now.
Feel like these public statements aren't worth too much. Lance Armstrong was vowing to be clean for years and when the first cases came up he was still vocal against it. Guess how that turned around?
