no one is arguing against nature - no doubt kids are bigger now than ever before - and harder and harder for a smaller guy to compete against a 6 foot 4 long pole who can also run with the wind., however - there is some truth to the fact that 6 foot 4 may have a tougher time defending against a smaller attackman who is actually tougher to cover than a bigger guy due to the size. im not saying its the norm, but some of these kids can get so low, it makes it harder for these bigger guys
