This is actually a clever decision. He wasn't sacked, so can have his future role. It doesn't mean we shoehorn in another coach in time to get hammered by saints and cas, but also means we will have a much needed change of coach.
I don't think Agar lost the squad. I think if anything, he was too pally with them, and not a coach they were afraid of.
Time to put the playing squad on notice. We need an outsider who will come in and objectively look at the squad, irrespective of previous performances or squad numbers.
