It's not where the guaranteed money stacks up against real life, it is what percentage of guaranteed money against the total economic market of the game and
if you wanted how that % would then equate to the real life guaranteed money contracts against the total economic market of the real NFL.
That's one of the problems that people seem to mistake with Madden often. They assume a direct correlation between the game and the NFL when they should be looking at the percentage of the event within all the events of the game and then comparing that percentage to the percentage in the NFL. That's why it's a simulation
(if it's correct, that is)
