I believe any drop in import numbers is maybe an answer to the continuing loss but it will not win trophies.
For instance, very simply, excluding MBA enticements etc..
The Devils will budget the number of imports to their projected average attendance = 1600 * ticket price = 8 CHL / OHL / College level etc
Belfast / Nott / Sheff, 4500 (+) * ticket price = 8 AHL / ECHL / ex NHL level
If a strict wage cap is enforced and audited, depending on the cap, then it's clear that Belfast, Nott and Sheffield will make their owners a profit.
However if it is not enforced then we are back to square 1.
I haven't included Brits, clearly with more slots open for Brits it will help to develop the game but the top brits will become even more an asset at a higher price.
Summary, Enforced and Audited wage cap = stability for "2nd tier" Elite teams and profit for others
