I'm quite surprised at that result actually. Sharpshooters had HCA + Pace GDP, and in theory the stamina advantage in the final quarter and overtime, yet thanks to the ref calling a large number of shooting fouls against the home team (So that's what started the riot at the Ring last night!), you pulled through.
I agree with the idea of not risking game 3 in this series even though you need the money. You should still get enough money from game 2 to just be above -500k at the financial update, and you'll be good for money next season. I can tell you that the salary floor in division II is about 190-200k, so if you wish to keep some of the players in your squad and still make money, you can. Selling only Monaco would be the easiest solution, but you could probably also sell the six oldest players in the squad and still come out under the floor once the new salaries for the season are calculated...
