Packers quarterback Brett Favre is retired.  Colts quarterback Peyton Manning isn’t so sure he believes it.

Manning recently explained that he usually writes a letter to players who have retired.  [Editor’s note:  A letter?  Does he send it by Pony Express?]  Manning says he has yet to pen a letter to Favre.

Manning doesn’t have any inside info; he’s just taking the same wait-and-see approach that the rest of us have adopted, given Favre’s equivocation on the subject in a couple of interviews since he announced his decision to leave the sport.

Video of Manning’s remark can be seen on NFL.com.
