When McCarthy first became available, there was that little blip of a story that the Saints were slowing down the process with McCarthy out of some concern that Loomis has a son that works for the Cowboys.
There have been times when a team has decided to hire a coach, but are coy about it until they satisfy the Rooney Rule.
I hope this isn't a situation were the Saints did something with McCarthy that could be considered tampering, so they're playing coy like they aren't even that interested in McCarthy.
