So why did Cam re-sign?
Imagine him with Arenas or Chip Kelly or Josh McDaniels, in those offenses. With those supporting casts (even though the Iggles are 0-2). Im not sure why Kelly wanted Sam Bradford.
I think it speaks to Cam's character. Yes, Cam is glamorous and flashy. He's an entertainer and a showman. But he's one of the most selfless players I've ever heard of.
It seems like every (true) story on him off the field involves him helping his community. He doesn't get into fights or have any drama. He's not in the tabloids for banging celebrities.
When he was at Auburn, he volunteered his free time at a local elementary school. At Carolina, there are numerous stories of him helping people in need and just being a positive role model for the city of Charlotte.
I think Cam cares more about his identity in his community than he does winning football games. Because you're right, there's no football reason for him to stay at Carolina. They're a dumpster of an organization with a lame-duck coach. He could have easily demanded out and gone somewhere to win a Super Bowl.
