It is the great holy grail in basketball analysis: How do you translate statistical value into a monetary figure? Can you predict what a player should be paid?
That would help solve a lot of the calculus of knowing when to let go of and keep players. How much to pay them and how much not to pay them. A lot of teams would love to know exactly how much to pay a player.
Really assessing value comes down to comparing players and figuring out whose productions is worth more or whose production is worth less or how exactly to value it.
