I am trying to come up with a formula on excel and any help would be much appreciated.

There are 4 columns titled: Player Name, Player Position, Projected Points, Player Salary.

I have a total of 121 players that consist of Center, Forward and Guard positions. Each player has a position, projected points value, and salary value.

I need to know all possible 8 player combinations (lineups) that have the highest projected point value with a total salary under $100,000. The 8 player lineup will consist of 2 guards, 2 forwards, 2 centers and the final 2 can be any of the 3 (utility).

Any help is much appreciated
