Who will win Super Bowl 50 comes down to old vs new. Cam Newton, the newly minted MVP vs Peyton Manning, 39 and way smarter than he is talented now then he was in his prime, trying too ride off into the sunset with a Super Bowl trophy. The key to this game will be the Broncos defense and Von Miller vs the Panther's offense with Cam Newton's combination of his improved passing game and making plays with his feet. Unless Manning can matriculate (late great Hank Stram, Super Bowl 4) the ball down the field and take a lot time off the clock while scoring, the Panthers quick strike offense will be too much to handle and tire out the Broncos defense.
Take the Panther's plus 5.5 and this game should easily top the 43.5 O/U (Super Bowls tend to be high scoring).
Enjoy the game and remember kids, Gamble Responsibly :)
