Peyton Manning will not win the MVP or lead the Broncos to the Super Bowl
Yes, of course he's an upgrade over Tim Tebow—Manning could suddenly decide to throw lefthanded and he'd probably be a more effective passer than his predecessor in Denver. But he's 36 years old and coming off an injury that threatened his career. He's admitted that his velocity took time to come back (Peyton Pennington?), and he doesn't have the weapons in Denver he had during his Indianapolis heyday. A healthy season and a winning record seem like the best possible outcome.
