I agree.. I've always said 9 ball is about advanced position play and running out. 8 ball is finding the path of lest resistance and patience. If you try the early run out more times then not you lose.
Good thread. I see it in 8-ball a lot. In games between good league players, whoever starts shooting balls first typically loses, because they can only get out maybe 1/4 of the time with 13-15 balls on the table, but they can get out or play an effective safe 3/4 of the time that their opponent only has a ball or two left.
I think social norms are part of the issue. It's just not considered socially acceptable to play a safety and lengthen out the game unless it's really necessary. You should shoot until you miss, and only play safe if you don't have a shot. Not saying I agree with that, but it seems to be the norm.
