In 1912 (long before Landis) Cobb attacked a fan in the stands and was suspended. The fan was indeed handicapped, but he was also hurling vile words at Cobb, who wouldn't put up with it. His teammates went on a one-day strike, then came back when told they would be banned from baseball if they didn't. Cobb did not escape suspension, he served it. The allegations against Cobb and Speaker in the mid-1920s came from another ballplayer, about a game several years earlier. It was that one player's word against theirs, hence insufficient evidence. Landis didn't hesitate to punch out the big stars (like Ruth) when it seemed warranted. The stats for Jackson in the '19 Series don't suggest he did anything much to help his team win. I don't know that he denied throwing the Series, some sources claim that. But did he keep the money? Far as I know, he did. There is a rule that banned players can't be in the Hall, because their actions are ON THE FIELD, and are a stain on the game.
