Honestly I think so, princeton should be the best one to use a little bit more the PF; just an info about motion vs r&g: do you think that playing motion the PF takes more shots that playing r&g? There is an interesting theory in Italy, the PF takes more shots if has a good lvl of skills in js/jr compared to the skills of the P-PG-SF. This is really interesting cause if you train very well all the team you can have a monster PF cause he will play often "outside" again an usual PF
