I have always been a big fan of Darren's. I took my 3 year old son to an autograph signing of his a few years ago and he took the time to give my son some attention instead of just rushing us through the line as quickly as possible. To this day my son's favorite player is Darren McCarty.
That being said, I think Darren's best days are way, way behind him. But, like someone else mentioned, if Joey Kocur can do something like this, I do not see why Mac can't pull it off if he works hard.
