What Loomis saw in DA was a good "coach" that could potentially develop into a good HC. He didn't, and so they know they were heard, plenty of people felt that DA's Raiders tenure was enough to prove that he wouldn't develop. Rizzi is another good "developmental" coach that Mickey would be wise to consider. Loomis' logic and reasoning were solid, DA was the wrong person and perhaps that Raiders tenure should have held more weight during decision making than it did.
Still, we shouldn't shy away from Rizzi just because of a previous mistake and his prior ties to SP. Again, if he's wrong he can just fire him to start 2026 and nobody will flinch.
