Ugh! This is circular. So you believe hiring a DC is not necessary. It’s uncommon for an inexperienced HC to also own DC responsibilities, but maybe Diaz is so extraordinarily talented that you’re right, he can do it all. Color me skeptical. If a DC does emerge, or if Diaz face-plants in 2021 with this approach, we can revive this thread and see who “has no sense”.Your question has no sense.
Manny Diaz is the HC and he will be responsible for the good and the bad whether if he hires a DC or not.
