Here's a .GIF of Peyton Manning dancing (to "Rocky Top," no less) during a lull in the Denver Broncos' training camp. Look at him go.You don't have to look any further than his hosting of Saturday Night Live to know that Manning is a big ol' goofball. He's got an effortless charm that is matched only by the effortless way he tosses the rock around the field on Sundays. His persona is that of a good-hearted dad who wears novelty aprons while grilling, or your favorite firm-but-fair middle school teacher.Last week, we learned that Manning scolded some attendees of his quarterback academy who were talking during a press conference. These talkers committed the ultimate infraction in Manning's eyes: not paying attention. You can goof off, but only at prescribed times, and only when you are Peyton Manning, the best quarterback on the planet. Manning could dance all through training camp, since he knows all the plays he's going to run already; the only thing he needs to do is introduce himself to the new guys on the team. Oh, you must be Emmanuel Sanders. Nice to meet you, have fun racking up 1,200 yards this season.Expectations are high for this year's Broncos, who won the AFC last year and promptly brought in even more talent. Peyton is the team's rock, an ageless, injury-less wonder (save that one hiccup that preceded his ouster in Indianapolis), but he's going to run out of batteries at some point. Unless he is literally a robot, at some point he won't be able to make those throws. That could happen after this season—heck, it could happen during the season—so the Broncos are going for broke and giving the man who has everything a few more receivers and a new defense that will get the ball back to him more frequently.Will that be enough? So far he's broken records as a Bronco, but hasn't brought home a championship. The Brinks trucks that were backed up to get new guys into that locker room are eventually going to stop beep-beep-beeping. There are any number of things that could go wrong and spoil the Broncos' quest for a crop of shiny Super Bowl rings. But you can't worry about that stuff, and Manning knows it. Control the things you can control, hope for the best, and dance around like your boss after his third frozen margarita at the company picnic while you can—it's the Manning way.David Matthews drafted Montee Ball to his fantasy team last year. Whoops. Follow him on Twitter.
