1) Double-plays? Hmm, could be interesting, I have to admit. I'm not against it.
2) Well, I guess if it hits the player and he whacks it away for four, that's kind of unfair. I suppose this is just covering for "intentional accidents" as some people call them. It won't hurt the game to make that change.
3) Now that's just silly.
4) I'm against this one, too. Because there are ODI openers all over the world who have been given their positions because they know how to penetrate the infield and get the boundaries, and this is taking all their hard work and flushing it down the toilet. This will, quite bluntly, change the entire ODI game strategy for every single player in every single team at every single level. I'm all for change, but not that much change. Maybe they should do things one bit at a time, for example, allowing the block of 15 overs to be moveable rather than just slotting them in one over at a time.
5) No harm in that one.
