IMHO, if MLB insists on excluding one of the members of its 4000 hit club from the HoF, then it should be the other guy. Pete Rose should be in the Hall of Fame - there is NO (none, nada, rien, bupkiss.....) evidence that Rose ever bet against his team, whereas, there's quite a bit of circumstantial evidence that Ty Cobb did just that more than once. AND they should enact a rule that every manager has to bet on his own team for every game.
