Youre telling me that you think Loomis picks the head coach, and manages the cap and thats it?

In the context of building the team, yes. He does a lot more than that behind the scenes, sure.

He doesn’t pick the staff, the players or the draft picks.

Aside from the HC, correct. I'm sure he's involved with some other staffing decisions i.e. the scouting department, training, etc but I'm speaking more towards the coaching staff and player personnel.

He doesn’t make the bone headed draft trades.

The buck stops with him in regards to the terms of trades, compensation and such, but the HC is the primary driver of proposing trade ideas.
