Newton is a young guy who struggled early in his career managing his emotions. By many accounts, he has done lots of good things in the community. Right now, his team is having a great year and he has emerged as one of the best players in the league. He is a bit of a showboat, but, so far, he has backed it up on the field.
Why not have fun while you can? I say give him the benefit if a doubt - I'd prefer to dwell on the positives. He's a rare physical talent who should be good for the game.
But this is the internet in the new millennium, the place where we go to render harsh judgments about people we don't know very well. We resent it when people do it to Brady or Gronk or BB. I don't know why people have to get so agitated about a young guy expressing himself. It's not like he plays for the jets or is NFL commissioner or something unspeakably vile.
Anyway, I hope the steamrolls Von Miller on international TV. That would be awesome ...
