by no means do I know anything more as I am still new, but I thought I could give another view point on the line-up, so here it goes.
PG: Langford because he has higher bh/pas/def he has a bigger difference in spd though
SG: Bishop because of his high defensive rating, and it looks as if his spd/per are increasing to help on offense as well.
SF: Newton high defense/ath, if Freeney increases his defense, he could start some games and give you a very rebound-dominant team
PF: Case, miller has very low defense, Lambrecht has good def,ath, but low bh/pas which i don't think would be great offensively for motion
C: Addison
again you have more experience, but I am just trying to give you another view to help look at things :)
