Caldwell turned to a theologian from the 1800s to make his point.
"There's a guy named Charles Hodge who's a great theologian," Caldwell said. "He said that you have to be able to 'exalt men without inflating them' and the other part of it is 'humble them without debasing them.'
"That's kind of a balancing act for us. We've got to make sure we make them feel good about what they're doing but not to the point they feel overconfident.
"We tell them the truth about the things they've done wrong, but we don't have to dog-cuss them and tear them down. It's a delicate balance to keep a team on even-keel all across the board. Never too high, never too low."
Caldwell said the ideal temperament is to come in the day after a game and not be able to tell by reactions whether the team won or loss because the players are all "focused on the next game."
As for handling praise, Caldwell added, "Flattery is much like flowers. You smell them but you can't eat them."
Caldwell was noncommittal when asked whether quarterback Matthew Stafford will play Thursday at Buffalo.
"That remains to be seen," Caldwell said. "We haven't made a declaration in terms of who's playing.
"It will be depending upon who we want to see and need to see, and who we don't need to see at this particular time.
"A great majority of guys will probably get some playing time."

-- Running back Reggie Bush was back on the field Tuesday, but he did miss a couple recent practices.
