Well, for some players I'm sure that's the case. Probably for me too.
But even with strong position play, after the break you're sometimes looking at a testy one ball. Not necessarily your fault, stuff gets kicked around. You'll also be looking at a tough shot after a push, if the opponent lets you see the one. And occasionally someone dogs a safety and leaves you a look, but it's still a shot only a mother could love.
Saying it another way, for every 50 balls run, 9b will have more testers than both straight pool and 8 ball (assuming the same guy shooting all three games, and he's about equal skill level in all of them).
prove it.................if you haven't already figured it out....I think 9 ball is the easiest of the games.
