Dedicate One Game A Year To Salary
Instead of a salary, call it a bonus. Take all the revenue generated from Senior Night, or a bowl game, or even a preseason tournament, and just use that to pay the players for the season. It's less money, but it adds extra incentive again if it can be directly linked to a certain game. NFL players get a bonus for playoff games, baseball players get a World Series share. Give the bball team some money if they sell out the stadium on a certain night - it's like a bake sale for 7-footers.
