A few points here about Pete Rose.....
1. Betting on games does have an effect on baseball. While betting on a game may not directly effect the outcome of a game, it hurts the game's integrity. Integrity is VITAL to the health of any sport. How does gambling effect the game's integrity? It doesn't matter if Rose actually threw the games. If it is known that a player, manager, or whoever bets on a game, then the fan immediately begins to worry, "Am I seeing a legitimate athletic contest?"
2. It doesn't matter that Rose didn't throw a game. There's a rule in place that says no gambling. I don't know if Rose bet on baseball or not, but if he did, then he broke a written rule.
First off, throwing the World Series and gambling are two different offenses. Throwing the series is far worse than betting on regular season games, and you can't really compare Jackson with Rose.
With that in mind, I see some falsehoods in your statement. It is NOT painfully obvious that Jackson was not involved in the scandal. Look at the facts.
1. Joe Jackson sat in on the meeting where the means of throwing the World Series were discussed, along with seven other players.
2. Jackson received $5,000 on the pretense of throwing the World Series. It doesn't matter at this point whether he did anything to actually throw the Series. HE RECEIVED MONEY FROM GAMBLERS.
3. Jackson did hit the Series' only home run. In game 8, with the White Sox already down by five runs.
I've never heard anything even suggest that Jackson wasn't even involved in the scandal.
