I think the short fences are important to the game, not for the glory of hitting more homers, but to keep kids that swing away in the game. Dominating pitching already created a shift where 50% of the offense being played against a great pitcher was the short game. If we don't want the game to become 100% a track meet where speed is all that matters and batting technique is irrelevant, coach just wants fast players that can bunt/drag/slap(yes I know there is technique to those skills as well). IMO if you moved the fences back to 280-300 you would be encouraging more short game which doesn't need further encouragement. I like the short game's role in our sport right now, but wouldn't want to see it become even more prevalent. There is something special about the duel between a batter and the pitcher and bunting a ball and hoping to leg it out seems like a copout at times. If it's not done as a sacrifice, but as an offensive strategy, your basically saying I like my odds of beating out a bunt over my odds of standing in and hitting the ball. In this sport, very often that is an accurate assessment of your odds, but I wouldn't want to see a game that is 100% bunts/slaps and I think you would push away great players with average foot speed. Right now there is still room for players of average foot speed, because if you put the ball over the fence, it doesn't matter how fast you run.
