The NFL offensive blocking is played differently; they use their hands instead of their head and shoulders.

And as a true athlete, mistakes haunt you forever.

Everyday I walked on to the field I was the best center.

You must also give mental and physical fitness priority.

I also played in the 1967 Super Bowl against the Green Bay Packers.

I think the tougher the challenge the better.

If the entire team can feel the same way about these things, you can consistently remain a winner.
