Saints planned to interview Mike McCarthy; McCarthy didn’t garner enough interest from Saints and will take a year off

The cap went down ~$15 million. All other teams had to deal with it as well. Only one still has it as an excuse 5 years later.
Go ahead and ignore the point then, which was that Covid hurt that strategy more than other teams. That is a fact. They were already committed before Covid hit and the cap going down hurt teams making full use of the cap more than those who weren't.

I'm not addressing what happened after, which is a different discussion.
