Trying to remain cautiously optimistic, but in reality very underwhelmed.
Would have preferred a complete change of guard along the lines of something like Adam Peters as GM and Ben Johnson as HC.
The defense was good, so keeping Mayo as DC would have been fine.
I'm a bit concerned his thought process might be too similar to Belichick's, as that is the only person Mayo has ever worked for. If Mayo emulates BB the DC, that's fine; he can't fall into habit of mimicking BB on offense, as HC, or as a talent evaluator in personnel decisions.
