1st you have to define "pouting on the sideline".
I've seen everyone from Tom Brady, to Ryan Mallet either cuss out teammates, or just stand their with a angry scowl.
I remember listening to the Charlotte sports radio show "The Mac Attack" back in 2013, and the White host of that show Mac-something(forgot his name) finally conceding that perhaps the critiques of Cam Newton being racial. Because even he was incredulous at the venom being thrown at Cam on a weekly basis, that wasn't hurled at White QB's who played just as bad or worse than Cam.
You can only believe he brought "so much on himself" in a league that has historically proven that it treats Black QB's differently. The NFL and White fans won't get the benefit of the doubt from me. Nope!!
Don't pay him any attention. He's not better than white racist when it comes to Cam criticism. That's why everyone been calling this dude a c00n for the longest.
