Wow. Average size of Americans has no correlation to the outliers who are multiple standard deviations away from the average. Like the PFs and Cs in college and the NBA. Those guys are outliers no matter what country they are from, and our 2nd tallest NBA player was actually Chinese, so thank you Marillac for your equally pointless rebuttal, since the average clearly has no relevance in this particular conversation.
none of these stats or rebuttals say anything relevant to the issue of a perceived lack of american big men in college and the NBA, and none of us can even begin to analyze this without relevant stats in front of us.
I nominate Baldi to do the research and report back.
I agree, whether or not the average american is an inch shorter in 2011 than in 1975, is completely irrelevant. The population has expanded, and even with an influx of presumably shorter men, that shouldn't affect the gross number of men at the far end of the spectrum.
Without looking this up, I would wager that there are just as many 6'9-7'0 men in America today as there were 20 years ago. But in case you haven't noticed, the game is being played very differently today. Ball handling, shooting, and athleticism are at a premium. The game is less physical, played at a much quicker pace, and a preference is placed on offense at the expense of defense if necessary.
Big men are asked to do much more today, and in many coaches eyes they are better off playing an athletic 6'8 240 PF that can do a little of everything, than a 7 footer who can block shots but not much else.
Coaches are choosing athleticism and skill over size.
