"When something's not right, you have to make it right," Childress said. "This was the most unemotional decision I've had to make in this job."
Childress began his press conference by addressing the Moss situation.
"It didn't work out," the coach said. "Not going to get into any particulars. We have an internal process we go through.
"It was a decision you don't take lightly, but it was a decision I had to make."
Childress didn't mention the move when he told reporters Monday morning that Moss was staying back in the Boston area for a few days to spend time with family.
On Wednesday, the coach explained his actions.
"As long as the right people are contacted in the right order, I think that's important," Childress said. "I have to answer for my decision. It's not an attempt to deceive, just let people know who need to know. That's why he was not on the waiver wire that day (Monday)."
Moss' behavior during a post-practice buffet Friday and his postgame rant after a loss to the Patriots on Sunday might have played a role in his release.
When questioned about Moss' past behavior, Childress said, "I feel like I do a decent job looking into guys' backgrounds."
The release of Moss caught quarterback Brett Favre off-guard.
"Like most guys, a little bit shocked," Favre said. "In this league, you should never be surprised by anything."
Favre said Childress didn't explain the decision to the team, which went 1-3 after the trade for Moss.
"He didn't give any (reasons). Not that he should," Favre said. "As players, and I know fans as well, donât always agree with decisions. As players, weâre no different. Right or wrong, a coach or an organization has to make decisions.
"Weâre back to where we were four weeks ago. The fact is, 1-3 in the last four games is not what we had hoped for. Once again, not one man is to blame. Itâs a collective effort."
Favre did receive some good news Wednesday. Childress said his favorite target from a season ago -- receiver Sidney Rice -- will come off the physically unable to perform list Wednesday. The team has three weeks to activate the 2009 Pro Bowl selection, who is recovering from offseason hip surgery.
"He'll take some turns today," Childress said. "We'll see how he comes back tomorrow."
Favre's health, for the first time in two weeks, was a back-burner topic. He said he still experiences pain from the broken bones in his left ankle and heel, but "I probably should feel a whole lot worse."
As for obtaining Moss in the first place, "I thought it was worth a try," Favre said.
