Click on the link to Steelers Charity Auctions and look at closed auctions (you have to log in as ebay member to do this). One of the auctions shows a Ben Roethlisberger game used autographed Wilson NFL football. The Football is an NFL game model, but if you look closely to the pictures, you will see two large letter K's lazer engraved into the valve side of the ball.
The "K" ball was introduced by the NFL a few years ago as a means to stop kickers and punters from doctoring up footballs to resemble rugby balls and thus creating an equal playing ball for both the home and visitors kicking games.
The ball probably was game used since the "K" ball is not available retail from Wilson. However since Roethlisberger is not the holder, the only time he ever touched this ball was to sign it. Someone expecting a Big Ben game played ball should be pretty peeved right about now.
The teams aren't always right.
It's a pretty simple error, I wonder if Dave Bushing would have got this one right! (Ahhh, Probably not).
