I don't know of any player tendencies that directly effect FB opportunities. I do think that a combination of the FB/Offensive Tempo/Run Plays, and to some extent, Quickness Slider effect FB opportunities. Personally, I think that the Quickness Slider needs to be at 0, which is where I have it in my slider set. One of the things that the Quickness Slider effects is a player's jog speed, which is REALLY fast in the game. With this at 0, it really gives contrast between Quickness (jogging/walking among other things) and Speed (sprint).
I'm not sure about Shane. I the current game (4th quarter, 9 minutes left), he has taken a combined 17 shots in 47 minutes (5-5 on one team and 4-12 on the other), and 9 of those shots have been 3's. He spots up a lot on the permimeter and has a high 3PT tendency, so those are both reasons why, I'd guess.
Man, I ain't sweatin' disagreements. No theory is good unless it can withstand testing.
