when you play look inside its best to have SF-PF-C with good inside scoring
your guards should be good passers and drivers, and it is also good if they have inside scoring of 5+, but this doesnt affect the rating much
the fact that his inside defense isnt that good doesnt mean you have to play inside, if you cant mach his defense maybe you'll be better off playing for your strengh, but, its up to you to decide....
