On a recent episode of his "WOOOOO! Nation" podcast, Ric Flair stated that Randy Orton may be looking to lighten his workload a little in the near future. Flair compared it to the schedule Shawn Michaels had before he retired - work a number of shows and then get time off.
Orton is only 35 years old, but he has been an active competitor in the WWE since 2002 and the guy always puts on a great show. That is a lot of miles on ones body and I don't think anyone would blame him for wanting to lighten up his schedule at least a little bit.
The Wrestling Observer Newsletter points out that Orton has had many weekends off this year and that he is probably in a stable financial situation where he doesn't need to work as much either.
