I have actually, legitimately heard this is a consideration. Didn't know it was going around.... I can see it as a potentially positive thing as a movement towards getting more teams to try NPPL that haven't, but on the other hand I can also see it appearing to be the NPPL folding to the PSP's way of things.......time will tell.
1st we must remember that a tournament league is a business, which needs to find a way to appeal to as many teams as possible. More teams = more money = better events = more teams. If all the leagues have 44 or so of the same bunkers then 4-6 signature bunkers it accomplishes 2 goals. 1st it makes it easy for fields that have only 1 airball field to buy a upgrade kit and suddenly have the ability to format for both leagues, or have a close approximation even with no upgrade kit. 2nd, by having this ability, more teams can practice the format of an upcoming NPPL in their vicinity. With the field size at 170x100 it fits in the old NPPL field layouts as well as PSP layouts. As a business move, this should increase attendance since any field who had formatted for the old PSP 120x170 can quickly rearrange and have a NPPL layout giving far more teams ample ability to practice and generate more interest. Also, im sure their signature bunkers would provide for the extra size, but that is conjecture of course.
