A lot of discussion about what a pass game coordinator is....
Is pass game coordinator above or below position coach? (actual question)
If it's above it might just be a way to hire laterally (like another qb coach? Hire him a step up as pass coordinator, want to protect yours? Promote him to pass coordinator).
That's just a wild broad guess, different coaching staffs operate differently.
Last year pats didn't have a defensive coordinator.... Not because bill took over HC/DC, he didn't even call defensive plays.
The olb coach did, and come time to hire new HC, ILB coach took over instead. Come time to hire new DC, the DL jumped ahead of the play caller.
That olb coach is future huskies legend destined to surpass dad Steve belicheck.
Stupid drunk roundabout way of saying that different staffs have different responsibilities, probably has something to do with passing through.
