You can believe whatever you want, you can believe the earth is flat, but if you start saying there is evidence to support it and scientists who believe it I'm going to call those lies what they are.
Basically you can have your own opinion but not your own facts and history is based in facts. I can't say "Maybe SF won the SB in 2012" and have it to be an opinion, it's just wrong. First you multiple times tried to pretend 2014 was ancient history when we only had 2 seasons in between. Then you tried to add this one in despite us being the favorites to make the playoffs. Then you tried to pretend he didn't play well in 2014 when that is also provably untrue.
If you want to say Flacco doesn't have a switch he turns on to become great in clutch games that's fine and you are entitled to think that but you cannot pretend that it hasn't happened over and over because then we venture from opinion territory to false territory.
