This is too fun. I should have done this a long time ago. So now afterni spend a half hour to go over ten rosters completely and look up us census info and make all the calculations your response is... ITS ALL A LIE DARN IT! Well I confess I can not specifically speak t o how these heights are derived but you can bet I will now look into it. And return with something concrete. There is nothing wrong with having a theory. And thus one of yours may hold some water who knows. But you have to PROVE it not just present it. As for the major league pitchers I know personally I think all their heights were reported pretty accurately. But no matter what we may find on 'misreported height' there is no way it will even come close to evening out those numbers. That shorter group would only be bolstered by those listed at 5'11" and if your point is 100% correct 6'0"". And there are not even enough of those to bring numbers any where close to proportionate.
