Not a big fan of the 5 seeds possibly/probably earning more money than some playoff teams. Why don't the two 5 seeds just get 2 additional automated scrimmages with each other, splitting the revenue and eliminating the variables of the proposed new system? That way they get a reasonable sum of money but no more than any playoff teams. The logistics and structuring may not be there but it's more fair.
edit: well, I forgot that the first playoff game is do or die and it's only a 1 game playoff schedule for losers. Meh. I'd still probably prefer it.
That would have seemed like the easiest and most sensible solution. You have the 5 seeds play one friendly with revenue in the first week of the playoffs, and the 5 seeds plus the teams that lose in the first and second round (and consequently don't play the final) play another friendly with revenue in the second week of the playoffs.
That way the 3rd and 4th seed get at least 1/3 of an income plus the chance of playing in the playoffs (and the presumed better fan reaction) plus an additional 1/2 income, the 5th seed gets basically one full income (considering two 50% incomes) over the two weeks, and the 1st and 2nd seed get at least 2/3 of an income plus an additional 1/2 income. Obviously the more you win in the playoffs, the more incomes you have.
