This was a common argument early in the Pete Rose saga - if he bet "for" the Reds to win, it's ok.
Rose was a habitual gambler, probably still is. Those addicted to gambling don't bet to lose. If they do, their bookies, or other shadowy figures prominent in their lives, are eventually going to come calling for their payday. That spells real trouble.
It all breeds corruption and, if let unattended to, results in another Black Sox scandal, which would make steroids look like baby aspirin by comparison.
So, less than 24 hours after the Reds Hall of Fame opened an exhibit in his honor, Rose again succeeded in dishonoring himself, his city and his hometown team.
He's proclaimed his love for the Reds by admitting during an ESPN Radio interview that he bet on his team "every night".
Great. Good form Pete.
