He can even tell them what the program was like way back in 2009. Remember?
The Vols went to an out-of-state bowl, had a quarterback drafted, and actually made forward progress running the ball. Imagine that.
Chaney can also offer an eyewitness account of "Black October," the night Tennessee donned black jerseys and drubbed South Carolina. And he has a working knowledge of "Black January," the night former coach Lane Kiffin made his California gold rush.
Ancient history, you say? OK, then how about something more recent, like "Black November," when UT's 26-game winning streak against Kentucky ended?
Any newly hired UT assistant coach must be curious — at least from a professional perspective — as to how the Vols' last season ended with a crash for the ages.
One of the advantages in UT's limited access to assistant coaches is that subjects remain topical for months. So I didn't feel as though I was dating myself by asking Chaney how he had processed a 10-7 loss from three months ago.
"One of the hardest losses I've ever been a part of," Chaney said after Wednesday's practice. "It takes a toll on you."
There was plenty of blame to go around, especially for the UT offense, which proved itself incapable of scoring more than an offense so impaired by injury that it had to rely on a suddenly converted wide receiver at quarterback.
The last Saturday of November isn't as painful amidst the optimism of spring practice. Chaney likes all three of his quarterbacks, speaks glowingly of his tight ends, and is encouraged that his wide receivers are trying to block people. But while he prepares for the season to come, he accepts his share of responsibility for what went wrong last year.
"I'm trying to get (quarterback) Tyler (Bray) to take ownership of our offense," he said. "I have to take ownership of our offense that (scored only seven points)."
His critique extended beyond one game, though. He saw the Kentucky game as the culmination of an offense that was rarely on the cusp of competence.
"There are some things I would have done differently," he said when addressing the season-long struggle in retrospect. "We had struggled all year. I would have tried to show more leadership early on in some things.
"But we don't need to get into all my deeper thoughts and the demons I lay on the bed and think about. I'm a weirdo about those things."
From a fan's view, that's more commendable than weird. The last thing they want to hear from a coach who had anything to do with the Kentucky defeat is something along the lines of: "It was a tough loss but I'm not going to lose any sleep over it."
If you consider Chaney as weird, it's probably because you can't comprehend why he stuck around after a 5-7 season. The majority of the staff fled the scene almost as fast as the Vols left Bar Knoxville a couple of years ago.
"You can run away from it," Chaney said. "Or you can sit here, look it right in the face and try to correct it. That's the decision I made.
"When I came here, I wanted to stay here."
After just three years, he already has stayed long enough to qualify as staff historian.
