i personally make good experience with good shooting PF(give him a little range), even with two shooting and passing big i experienced troubles with playing princeton so that wouldn't be my first choiche.
hm...i think you're right, range must be the key...i wasn't thinking princeton it's too outside oriented and i don't have dwight howard in the middle :-) ...motion isn't so much all outside shooting, if you have good driving players, you will have a well balanced game...i just wasn't sure about the pf (both scoring bigs is too much for me).
by the way, who in the real world plays motion? OKC thunder? boston celtics?
hard to say, i don't follow NBA to much and Motion offense is more like a general idea of a gameplan then strict systems. Orlando is it definately not, since basic rule of motion is that everybody have to work for a shot and had to be in "Motion" for getting open. Also you try to get your players in the action on medium distance to each other, i believe orlando likes to use a spot up shooter in the corner often to open the field.
You work with lot of blocks etc., and need some people who understand to read the defence and the right spacing(classical 1-2-2/ or simpler said three out two in with the "point guard" in the back to protect fast breaks).
When you receive a pass, you can often wait till the other player on your team moved to the new situation but should be also keep your options open(pass-dribble-shot).
You see motion is pretty classical gameplay, and can vary a lot through the personal you have.
