I originally thought "My God, how could he be so stupid?" On closer inspection, he's being railroaded for the errors of the Player's Association. Seriously, if this story is true, and they did clear this OTC supplement for use, only to later find out that - Uh, sorry, it can cause you to test positive; Woops-a-daisy! - then there is no negligence on the part of Romero, only on the part of the Association. They need to pay the fine and be suspended for 50 games, not him.
On the other hand, he shouldn't be taking anything stronger than aspirin. He's making a 7-figure salary - there's too much at risk.
