Not playing any cards here, you've got what they call recency bias. You are fine with it now that it worked in the Chiefs favor. I'm neither a Bills fan or a Chiefs fan, just a fan that hated to see the game won on a coin flip. I felt the same way in 2019, that game was fun to watch and I would have loved to have seen Mahomes get another shot. Playoff games should not be won or lost on an OT coin flip.
I don't see it as recency bias. I see it as an OT loss in both circumstances. Does the rule suck, maybe, but they have all of regulation to get it done. And I was disappointed when it cost the Chiefs a trip to the Super Bowl, but wasn't complaining the rules need to be changed. I don't like the rule, but what's the alternative? Honestly I'd rather see an OT similar to what is done in college, but I don't understand where you draw the line? We hate games ending on an OT field goal, then it becomes the other team needs a an opportunity to get on the field so lets change things and say if the team that starts with the ball will get it back in the event they do kick a field goal on the opening drive. At what point does it end? It's almost as if what happens in regulation no longer matters, what's next? Play an an extra half?
As I said in the other post, I think the way it is done now is far from perfect, but at the same time the outcome is determined during the course of play. It's not like a soccer match going to penalty kicks or a hockey game going to a shoot out.
