Here's an experiment:
Go enter some giant free-roll and a $10 tournament with a huge guaranteed prize pool. I would bet that the top score (not the average) in the free-roll will have higher score. Now take the points that each player scored and their original cost and you can use a variant of the knapsack problem[1] to figure out the optimal lineup. You'll see that quite often the optimal lineup wasn't picked by anybody (mostly because the player costs are pretty good and the optimal lineup sometimes doesn't use the full salary).
