I like seven inning rule. Other than being a traditionalist, not sure why one would argue.
Why 7? Why not 6 or 8 or 5?
Why not allow a scheduled 7 inning game to be a no-hitter?
Why not change
all the games to be 7 innings?
Why shorten it to 7 innings instead of making double headers take 2 strikes for an out and 3 balls for a walk?
Hey, make extra innings have fewer fielders! That will increase the runs, just like running 3 skaters in OT.
Kid,
all the rules are based on tradition. Why not ditch any that make the game take longer?
