Bear with me if someone has posted this.
Just took a look in the players.dbf and found two attributes that's not in last year's game.
THREEPTATT
The lagest value is 59. Most of the players have large value are pure 3pt shooters like Brent Barry and Darrell Armstrong. Those who have zero are almost all big men who can't make 3. I think it control how often the player will try a 3 when he has open look.
THREEPTSTY
This is a much interesting one. It's from 1 to 9 for all players except 3 guys. 1s are 3pter like Mike Bibby and Jason Williams, 9s again are big men as Pau Gasol etc. The 3 players that's not in this range are 11 Shaq, 12 Reggie Miller, 13 Peja. Yes, two best 3pter in the league have their own value and the worst too. If I am right, this should control the clutch performance for the 3 point shooting.
I don't have time to do some experiment yet. But you guys can try edit that yourself and see what happen. Don't forget to backup.[/b]
