Within stadiums during games, cheering can help inspire players and disrupt their concentration. Beyond that, cheering serves only to bolster one's own self-esteem and show homage for their favorite team.
Fans cheering outside the stadium does not create wins or losses, even from their living room couches or game bars.
Likewise, fans cheering for or against their teams winning or losing has zero effect on franchises' drafting order. And couching cheering has less than zero impact on which player franchises pick before, during or following the draft.
So the answer to the thread question is either "No since cheering doesn't serve any useful purpose beyond making people feel happy inside" or "Yes because some people believe in fantasy outcomes and that delusion is safer for everyone else who knows better."
