I see it as a lack of perspective. Cam's behavior is a maturity issue.
After the initial press conference, I didn't agree with all the criticism and I didn't think he owed anyone an apology. I thought if he owned it, so be it. He came out later and did that, admitting he's a sore loser. Ok then.
But he tipped his cards when he took it a step further with "who's to say your way is right?" That attitude completely misses the point and shows the lack of perspective.
The fact is, all people are entitled to their emotions. When we watch several people over a long period of time experience similar circumstances, we also see how they respond. It's in our brains' hardwiring to compare and contrast things, to recognize patterns, discrepancies, and outliers.
We can identify several QBs who handled a SB loss with emotions and body language we recognize as requiring maturity and perspective. Cam's emotions and body language resembled that of a child who just got grounded for not doing his chores. Cam is an outlier in that regard.
So he owned his behavior; he knows who he is. But he still doesn't understand how his actions fit with the rest of the world around him. He either thinks he's above being compared to others, or in some way he exists in a vacuum independent of and unrelated to the others.
"Show me a good loser and I'll show you a loser" ??? Russell Wilson handled the XLIX loss – one of the most shockingly disappointing finishes to a Super Bowl in 50 years – with great command of his emotions and a forward-thinking, positive perspective. He has a Super Bowl ring. Who's the loser, Cam?
