Yeah, tons of bottom level players seem to take on huge salaries to get high level trainers for cheap.
Sell what is sellable, fire all your staff on Sunday night, fire any players who don't sell and hope for the best.
There's not need to have that many players on your roster.
To be honest, I don't know if you're going to be able to pull this one out. Keep in mind that i haven't seen your financial statements but I don't know how likely it is that you'll be able to make the $250k plus staff severance fees that you will need to get above negative $500k. Maybe your top five guys will generate it, but this is not a great time to sell.
This really might be a lost cause.
