You know what was sad? The last year (when he was still on the team at the end of the season) he was with the Blue Jays, the Blue Jays Store at Rogers Centre was heavily discounting his jerseys. It got sadder that his girlfriend (Kara Lang) was at Rogers Centre and got to see his jerseys being sold for $9.99 -- and no takers -- a crap load of jerseys, including the red ones, that no one wanted. Not even for a single Sir John A McDonald. She was really upset about that.
Now for anyone that has (or had) a Roy Halladay jersey....that's a whole different story...they were always valuable, and even more so now.
