You would care if you're one of the guys not on PEDs trying to work your way into the majors, competing against all sorts of PED cocktails.
I don't mind the 50 and 100 game suspension, but I think there should be a substantial fine that relates to what the players salary is... a lot of these guys are getting HUGE salaries after they put up big PED-induced numbers, so they should have to give it back.
