Formula Based Upon Number Of Empty Cells?

I am creating a fantasy football draft board using excel. To keep it short and sweet, each individual team (one per column) has a $200 budget to draft players. Each team must fill 14 roster positions (one per row), but here's the catch; you must spend at least $1 on all of the 14 players on your roster. So you have a maximum bid amount which is your remaining budget subtracted by $1 for every remaining spot you have left to fill.

I have already created a "remaining budget" field which subtracts each drafted player's inserted dollar amounts from the $200... easy. Beneath this, I'd like to create another cell per team that tells you your "maximum bid," which is essentially 200, -1 for every cell that remains blank. I have played around with the conditional IF formulas but cannot seem to have it account for multiple cells.

As a workaround, I have made columns hidden beneath the board which contain the conditional IF, ISBLANK fields which are -1 if true and 0 if false. Then creating the "remaining budget" field that subtracts these values from 200. This works, but it's not perfect, as when you have multiple players you still need to draft and you've exhausted your budget only saving $1 for each, it overstates your "maximum bid" by $1, or when you have $X left and you need to only fill one more spot, it ill tell you your "maximum bid" is $X-1.
