As you said, they haven't started "YET". So your assessments here of Hayes and Provy are speculation.
I get your point about "picks", but you cannot have a rebuild with Hayes still on the roster. He has to be the first move. And whether you like it or not, I think the way he has been used in the second half, shows the Flyers feel the same way. I'll double that by adding TDA
DB has has some time to set a plan in place. At least he better have if he wants to remove the interim tag. And it seems likely he has relayed that plan to his coach, who has responded by essentially putting these two players in the doghouse.
