Ryan Roberts signed a minor league deal with the Diamondbacks in the winter of 2008 and made the 2009 Opening Day roster. 2011 was his most memorable season with the D-Backs, but half way through the 2012 season he was designated for assignment and was gone. He didn't start his career with the D-Backs or end his career with the D-Backs, but it was during his time with the D-Backs that I started collecting him.
I also collect players like Ken Griffey Jr., Mike Piazza, Paul Goldschmidt etc., but lots of people collect those players. I don't know anyone else that collects Ryan Roberts.
Do you have a player that you collect that nobody else does?
