I guess I need to return all my NFAA 20 pins and bowhunter freestyle tournament trophies because I won them back when pin guards were against the rules, and there were no round pin guards even if they had been legal. No way I could've shot well enough to earn them without a round pin guard. [8D]

.....and facemasks in the NFL have "caught on".
