*insert joke about title* but in all seriousness, does size make a difference when it comes to where you play your guys? I have a 5'7 PG who would probs be more effective as a 2, will it matter that hes short? Or a guy whose 6'4 as a PF that I want to play at Center sometimes?
Can they be just as effective as they would be at their natural position or will their height throw them off.

in short, size does not matter at all. it is never a factor in game play.

the longer version is that size only matters in recruit generation. its possible that you could deduce some info about potential from size, but i am not sure. it depends how it was coded, realistically it could go either way. if any young ambitious coach is interested in researching and possibly exploiting the possibility, send me a site mail and we can talk through how to figure it out! we'd simply have to determine if it was just starting ratings that were based on size/weight, or if it was final ratings. and also, if correlations like the def ath correlation were only based on starting ratings, or max/final ratings.
