Ben's immature, but very strong minded. Cam's immature and hasn't shown any signs of being mentally tough. Immaturity can win, soft mentally can't and you cannot predict whether that can/will be fixed or not.
This just isn't true. Michael Jordan was an ### and a poor loser and was as metnally tough as the human species can display playing a sport. Cam was down 21 at half to the 2nd best team in the nation, and came back. He won a national champtionship game while a media frenzy was going on around him. Cam has won at every level. In college, he has two national champtionships and never spent more than a year at each school.
When you decide what mentally soft is, and what immature is, you are cherry picking.
No offense, but I can't take anyone too seriously on the subject, that suggest Cam Newton doesn't have what it takes to win. The kid hates losing, and doesn't handle it well, yet. LeBron James went through it too.
Again, if Cam Newton is good enough to win football games, all of this goes away - it did with Jordan, Kobe, Eli, Ben, etcetera. If he's not, he will be a more productive Cutler/Rivers, and their fantasy points count as much as Tom Brady's.
