its just against controversies, didnt they say that Pete wont last long with his backswing back then? i believe if proper exercise and training is done by the bowler, there should not be any problems throwing a 16lb ball.
people who gets injured in bowling, is due to few reasons i believe:
1) no proper warm up, how many local hacks have u seen arriving at the alley late, puts shoes on and goes hard on their first ball?
2) accident, i do accept the fact that accident in bowling can happen, sticky lanes, off timing and hitting the ankle or feet, too much turn and break a finger.
3) going against physics, i believe, with a style like Barnes or Bohn, they can just throw the ball all the day long, however, Smith or Jones might find that a bit more challenging.

When a house bowler misses the mark, misses the break point and strike, for many ppl its called a wallshot. When a pro does that its call adjustment
When a house bowler gets his finger stuck in the ball and fall on the lanes, for many ppl its called lame bowler. When a pro does that its called the Machuga flop! ha i like this one.
