Pitching wins championships, this is pretty much connected to Basketball in Defence wins championships. The truth is neither is really true. While yes your team needs to pitch well enough to win, it also needs to hit well enough to win. Yes, great rotations can nulify good lineups i'm sure the it's also right that great lineups can hammer good pitching.
Instead of saying pitching wins championships, a better phrase would be "Execution wins championships".
Any more Myths you'd like to point out?
