I hope they don't go to 7 inning games all the time.
A big part of strategy when the other team has their ace on the mound is to keep it close until the bullpen comes in.
With 7 inning games, that doesn't happen.
I'm ok with 7 inning games on double headers. I am sure the players love it.
It's nice for the fans that the second game isn't all bench players too, since the first game is only 7 innings, many starters can play both.
I love the DH, I have been wanting that in the NL my whole life.
I thought the extra runner on 2b in extra innings would be stupid, but I actually like it. It makes extra innings more exciting, and it also helps prevent those 14-18 inning marathons which wear out the players.
Don't like the reliever has to face 3 batters minimum, but I could live with it.
