This is beginning to venture off-topic but I don't understand why it would be "horrible" and you don't make an argument at all as to how these rule changes would "destroy baseball". From where I sit, what I proposed doesn't change a single thing about what skills the players must have to play the game; pitchers would still pitch, catchers would still catch, batters would still bat, fielders would still field, base runners would still run bases, managers would still manage, coaches would still coach, nine or more innings would still be played, etc. etc. Also, the changes I proposed made not altercations to the rules of baseball itself; it's still nine innings to a game, three strikes to an out, four balls to a walk, hit-by-pitch to a base, foul pole is fair territory, over the fence between the poles is a home run, no temporary situational substitutions, and so on. It still sounds like baseball to me. I don't see what about the game of baseball got destroyed.
Steering back on-topic and to preemptively respond where I'd guess you'd go with it - the baseball has tradition and that the tradition is fundamentally ingrained into the sport argument - it again highlights the difference between baseball and football. Baseball, from my vantage point, is entirely too grounded in tradition and as such is change-resistant to a fault, to a point where the game is ploddingly slow to make even the most obvious yet subtle changes (what I propose I recognize doesn't necessarily fit "subtle"). Football, on the other hand, isn't afraid to be experimental. Football doesn't always get it right with said toying around, but football isn't afraid to admit errors, football isn't afraid to challenge conventional wisdom, football isn't afraid to go against the grain in the pursuit of something that may just very well be better than what exists today.
Forgive me for waxing philosophic for a moment there, but I felt it was necessary to further illustrate my point.
