Sterling Sharpe, Charles Woodson, Clay Matthews--Common Thread?

What do they have in common?

For much of their Packer careers they didn't participate in many
practices with pads.

Which has often made me wonder ... is part of their greatness due
to the fact that they didn't get dinged up or worn down each week on
the practice field? And maybe they had fresher legs on game day, as well?

We've decided to put the best brains in the universe on this theory by
posting it on X4. Don't disappoint me!
