Statistics from my LI games this season:
PG 15.5 FGA% (50.4 FG%)
SG 22 % (41.1%)
SF 20.1 % (55.1%)
PF 21.5 % (48.9%)
C 20.9 % (60.1%)
So the FGAs are pretty evenly distributed. I don't know if LI generally looks like this or if it's just because my team is very deep and I have a lot of good inside players, especially on the SF position.
