Regarding Stanton 2012 I don't think an injured All Star needs to be replaced by someone from the same team. That would be silly and would take away from someone more deserving.
Remember that most injured All Stars still appear at the game in the introductions.
In 2012 it's not that we didn't have a representative that year, Stanton was still an All Star it's just that he had knee surgery so he wasn't able to travel to the game so we weren't physically represented but we did have an All Star in 2012.
That year I was bugged that we had a new ballpark and new uniforms yet in the ASG it's like the Marlins were nonexistent but looking back it was a simple foreshadowing for our time as the Miami Marlins under Loria... nonexistent and irrelevant.
