Wil, sorry, I have to disagree. As someone who has always, and still does, play several different sports, mainly basketball and football, trust me, they are getting bigger and faster, not just bigger. It's hard to determine the knowledge factor you brought up, and I might slightly agree with you that yesteryear's was a bit smarter, but thats only because they depended on "thinking" more back then than just "reacting". But, here's an example of today's players getting bigger, stronger, and faster. I'm only 5'9, and I used to dunk any ball I could grasp in my hands. Put simply, I was the fastest and highest~jumping white guy anyone around here had seen.(Ive met one other) I grew up playing in the "section", and even black guys used to say they "never seen a white guy move like that". Anyhow......my point is, I'm still quick and have some of my vertical left, but..... playing basketball at various places now, a lot of the time are with much younger guys, and even kids in high school and just out of. A lot more of these guys today are similar to how I was, when it was rare for a white guy to be so quick and jump so high.Even though I can still run with them, They are running just as fast and jumping as high as I used to years ago, when it was uncommon. It's hard for many to understand by just "watching" players from different eras, but anyone that knows from "experience", will tell you exactly as I just did.
