Hey Tommy, I hope my post didn't sound like I was calling you out.. It wasn't my intention at all, I was just making a general point.
I hear the points about rule changes, but very hard to enforce anything and I feel detrimental also.
I personally LIKE the fact that you can deliberately hurt your opponent with strategy. It adds a new dimension to the game! Bowling as a 100% offensive game isn't nearly as interesting a multi-dimensional game. Assuming the status quo of the balls remains, pro bowlers in the future will have to be multi skilled to survive.
Offensive game, as has always been the backbone of the sport. Shot making, managing the lane for yourself.
Defensive game, strategic play for taking your opponent out of his comfort zone, be it psychological (going on for years already) or my trying to hurt his ball reaction.
Counter-offense - in short, the ability to deal with your opponents defense. The physical tools to play the lane however the match plays out (i.e. the middle of the lane gets fried, you gotta make the move right to compete you need the tools!) and also the mental toughness to deal with anything your opponent throws at you.
Just ask the games trash talkers of old and new whether they had a 'defense', Big Ernie S, PA etc.
