Name him? That's a near-impossible question to specifically respond to. The question could come from many different coaches. The entire NFL knows that McVay is going to be HD passing at all times with a dinky sprinkle of run plays. Making our opponent's week of preparation easy for them at all times.
I just answer your question my way....
I prefer an HC who actually has enough brainpower & enough self-control to realize that in order to win the ring he has to develop a running game from the beginning of OTA's, prepare to have more than enough RB's to run it due to numerous injuries that take place in this position & an OL that knows how to effectively run block. HC that will use it & keep it well greased helping the OL work out the run game operation throughout the 17 games. The OL operation takes time & actually use.
Having a primarily passing offense depending on wide receivers as the main producers will get you the type of team the Ram have had now since the beginning of 2019.
A good blending of running and passing with the primary design being "run the ball".
