Archie, who appeared on ESPN's "Mike and Mike" radio show Thursday morning, was asked if he believed Peyton had made up his mind about retirement.
"Maybe not totally," Archie said. "He probably envisions himself getting good and healthy. If he is good and healthy, can he play? I think he pretty much knows that it wouldn't be with the Broncos and that would be another thing, to change teams."
Archie said other teams had interest in Peyton before the 2015 season. The Broncos asked Peyton to take a significant pay cut that was eventually negotiated to $4 million. Peyton still has one year left on his contract with the Broncos -- with a team-high salary cap figure of $21.5 million for 2016.
And while Archie said he believed other teams would have interest again, he doesn't think Peyton would want to go through the process of switching teams for a second time in five years. Peyton signed with the Broncos in 2012 after a high-profile free agency tour.
"Now, he had some offers last year from teams, some teams talked to him," Archie said. "But I think that was going to be a lot of drama, again, to change teams, that he didn't want to go through. He did do that once, so I don't know that he would want to do that."
Peyton missed seven starts this season with a tear in his plantar fascia near his left heel. Archie said Thursday the foot injury has bothered his son "all year." Peyton returned to the lineup in the third quarter of the regular-season finale and has started the Broncos' two playoff wins.
"And the whole episode of having to work his way back -- went in as a backup for the first time -- so it's been unique, I think, as he said," Archie said. "But I have always told them to enjoy the journey. And Olivia and Cooper and all our family, we have tried to do that with them, with Eli too, and don't take anything for granted. ... He hasn't talked to me about next year, but Peyton, he will find the time, when it's over and he'll make a good decision."
When it comes to how he, and his wife, Olivia, will watch Super Bowl 50, Archie said he will have to find "that lucky spot," where he can stand at the game. Sunday will be Peyton Manning's fourth Super Bowl appearance to go with Eli Manning's two appearances in the title game with the New York Giants.
"Even the last few years, I didn't know if [Peyton] would come back and play after the neck surgeries, I wasn't sure he could," Archie said. "... So, we have always said don't take it for granted, but yeah, feel very fortunate that he has been doing this for 18 years. He's had a good run and played with some really great players and really good coaches and it just is, we'll look back and say it's been a really good ride. If he wants to play some more, we will keep supporting him."
