We all know that Peyton Manning stuggled early on that eventually lead to a few bad losses.  You can say it was his early knee problems, injured front line, no running game, or a lack of possessions with the ball to get into a rythm.  I say all of the above.  Experts have ruled Manning and the Colts as either done, old, or teams have just caught on to what they do after 10 years.  Sterling Sharpe from NFL.com recently answered a question in a chat (at this link  http://chat.nfl.com/front/archived_chat/47) about their stuggles this season: 

Hi Sky. Peyton Manning has had that year that we really didn't want him to have. It's just not there. People have caught on to what they are and what they do. It's no longer Manning to Marvin Harrison. It's now Reggie Wayne. Where they used to be able to balance the field between Harrison and Wayne, they can't win that way anymore. Harrison can no longer beat people.

There is no denying that Manning and the Colts offense has been inconsistent thus far.  The combo of Manning to Harrison has not been what we are use to, and  you can also say that Reggie Wayne is the number one receiver now.  But to say that people have caught on to what they are and what they do is a comment that is not expertise.  Teams already knew who they were and what they did, but it came down to execution and Manning and the offense wasn't doing that early on probably due to the problems I mentioned earlier.  Harrison can STILL beat people, but for some reason him and Manning can not just connect.  Going back to last week alone, Harrison had his guy BEAT several times whether it was on the sideline, down the middle, and in the end zone but the plays still went for incompletions  Two of those occassions the pass could have been just a bit better in my opinion.  The Colts can still win whether Harrison brings that balance to the field or not.  The Colts still won 13 games without that balance last year when Harrison was hurt, so again, Sharpe made another comment that is not expetise.

 When it is all said and done at the end of the season, Peyton will have his usual statistical year and the Colts will go to the playoffs.  Since the bye week, Manning has thrown for at least 2 touchdown passes while his interception total the last couple of weeks is at a stalemate.  He will have around 30 TDs and less than 14 INTs and if you look back at his overall Hall of Fame career, it would be just another season in the book.
