They're probably setup so that they offset each other (against other players incentives). If so it would be a complicated puzzle to get right, but i can see how it would work.
Take a simplified example, where the list manager decides that we're going to play either Tippett or McKernan each game - but never both at once. (for illustration purposes only!). Each could then have match payment, and other KPI incentives that add value to their individual contracts, but as a club we would only need count them once.
If this is the case then playing for a side like GWS or GC becomes even more appealing - a high salary, and nobody else to take your incentives away from you!

alex - I wonder if you're correct? It seems to me that the difference from highest payout to low payout could be in the order of million of dollars, and we could end up below the 92.5% threshold or whatever it is.
I also wonder about "front-loading" contracts. It seems accepted that it's done in football, but is it actually done? Perhaps you promise to play a certain player whatever is left out of your salary cap after all the incentives are done as a lump payment, and that gets taken out of future payments?
