Because the entirety of Cardinal fandom (BFIB Nation as I like to call them) has a weird obsession with how celebrated Ross was/is. They have no understanding that we, as a fanbase, totally didn't take any of it seriously and it was a novelty. They truly seem to believe he's seen as one of the most beloved Cubs of all time. It's really, really weird. They memorialize drunk driving murderers, we like to jokingly memorialize players who are good dudes on WS winning teams
