I don't think we'll miss out on anything even if they dick around for a week or so since nothing really happens in the first week beyond initial HC interviews.
With someone like Flores we're going to have to wait and see if he gets an HC spot or not, even if he doesn't want to stay in Minnesota. With someone like Leonhard he's probably going to want to wait until he sees what happens with Joseph and a possible HC spot, if Joseph leaves Leonhard would be the DC in Denver, which is probably preferable to somewhere else.
The only thing that could happen quickly in my opinion is jumping on a position coach on a team where there isn't likely to be any major movement, or someone currently out of the league/in college.
