It's an opening unless they've made the interim coach official.
I get it, and I do not disagree.
Could argue the other six teams do not have a head coach but Las Vegas does. However, technically it can be considered an opening because of the 'interim' label. Little bit of semantics.
When Rich Bisaccia was named the interim-HC, I thought it was 90-10% that the Raiders
would hire a new HC in the off-season. However, at this point, I would put it at 60-40%
they stick with Bisaccia; and those odds will increase if they win this weekend. So I am not expecting a 7th opening at this point.
I would be less surprised if a 7th opening came from another team.
