It might seem like overkill, but at least it’s not Brett Favre un-retirement rumors. ESPN:

One in-the-know coach says he has an answer to the most pressing mystery surrounding Peyton Manning — beyond what team will ultimately land him.

Duke coach David Cutcliffe, who has observed Manning work out and throw several times over the past few months in Durham, N.C., says Manning will have what it takes to play at the highest level when he resumes his career in 2012.

“It’s incredible how much progress he’s made in throwing the football,” Cutcliffe told The Tennessean of Nashville. “He’s gotten his arm strength back and his accuracy is there.

“I’m not an NFL coach, of course, but I think I know what it takes to complete passes in the NFL, and it’s clear that Peyton can make all those throws,” said Cutcliffe, who was Manning’s offensive coordinator at the University of Tennessee from 1994-97 and remains one of his friends.

Cutcliffe was also the coach at Mississippi when Manning’s brother, Eli Manning, played for the Rebels.

Peyton Manning wrapped up his latest free-agent visit Wednesday, leaving the Tennessee Titans’ complex after spending more than eight hours with team officials.
