Now this is pure speculation on my part, but could it be that they have made up their mind on whom they want it to be, but said person has to check with another employer to see if they could get out of that contract to take on the job, full time, at least until season's end? If so it could be Ennis (e.g. having to get out of his Fox Sports gig), or Hornby (having to get out of his Souths contract)? It could be someone beyond those two, but that's why I suspect no announcement as yet about an interim coach.
I mean how embarrassing would it be if they announced "[person x] will be our coach for the rest of 2026" and [person x] didn't take the job?
