Without turnovers there is a huge bonus to anyone who uses lots of possessions as that is their major downfall normally, not shooting percentage. Without a turnover penalty you can get all their usage almost for free if they shoot a decent percentage. Guards do get a bonus easily since they're not only higher on turnovers, but more likely to be taking threes.
3P% is obvious, just look for people who take nothing but threes. They'll come cheap likely because nobody pays attention to, and many like Bill Simmons ignore logic and deride, the best shot in the game.

http://www.basketball-reference.com/pla ... i?id=PDWu6I'd be loathe to give this away if I wasn't doing the NLSC league just for lulz and to fill it out, but Troy Murphy is a nice pickup in a league that loves the three pointer. Bombs threes like a guard, never turns it over, tons of boards. His non-defense is never going to hurt you in a fantasy league.
Matt Bonner would probably be a nice piece to have hanging around on the bench in a three point friendly league since nobody else will probably want him.
