Saints Cap Moves: Derek Carr restructured, Erik McCoy restructured; J. Williams released; cap space is at -$8,543,537

Straight from the article

“Although it felt like Carr himself might be interested in a change of scenery, the Saints essentially wound up exercising their contract rights with a “simple,” garden-variety contract restructure four days before the start of the new league year.”
Yeah, that's what I was referring to from the article.

I bolded the critical words in that quote. That is not the same as saying "I was told by someone that Carr wanted to leave." The author of the article admits it's what they "felt" "might be" the situation.

That is pure speculation on the author's part.
