Shannon is elite of the elite in terms of genetics, but he's also worked out consistently since he was a teenager. Nearly 40 straight years of dedication. Have to respect it.
Funniest comment he ever said on Undisputed when the topic was about a retired player possibly returning to the NFL.
A current player was the guest, and he said "Shannon, you're in good shape you look like you coukd still play."
Shannon "I just look this way, but I cant take those licks! That's why I retired! And that's why player X is talking about a comeback, but he won't do it."
