What happens when you go over your allotted cash flow for hiring coaches? Because on my offer sheet in one league, it shows me as having a little under $10M to spend before giving me the warning that I've gone over, yet I see another team who has over $25M spent on its coaching staff. Have I been gimping myself by missing out on awesome coaches because I didn't bid over this alleged cap? Is it not implemented? What am I missing here?

+1. I've never even been able to sign a coach :(

Your coach salary allotment is linked to your stadium attendance, because it's coming directly out of your team's cash flow. The range should not be huge, but if you're noticing a team using more coaching salary in use than you have available, that should explain it.

I won the SB in that league, so I sincerely doubt that a team who failed to make the playoffs is able to outspend me by more than double ($10M compared to $25M).

How much though does the promotion factor in? Using simpler numbers if you have an OC making 2 mill/season and I offer them 1.5/mill for a head coaching position ... would they be inclined to take my offer based on the title or stay with you for the $$$?

My understanding is that you must offer them a greater value than their current contract to accept a new position, even if it's a promotion. I doubt any coach in the NFL would take a pay cut in exchange for the stress of "upgrading" from OC/DC to HC, haha.

This is correct - a coach won't even consider an offer if it is less than he is making now.

good to know!!

So successful teams regards attendance can thus inflate coaching salaries meaning lower clubs can't match even if it's a promotion?

The range is minimal (I think it's capped at 5%). Some of the older leagues have pretty inflated position coach salaries because an older version of the AI incorrectly gave them the same salaries as head coaches. A good team can sign a coach to an inflated salary to help keep him from being poached, but that also makes it difficult for them to make good offers on other coaches, and he shouldn't be able to inflate all of his coaches above any other teams' ability to poach some of his.
