Either that or a sim franchise player's wet dream...
A group of people that pay attention to the whole league will miss out on some nuances of a particular team's playbook that die hard fans will see (you know, the ones that obsessively watch every play).
However, if I have to buy a PSP and PS3 to be able to create plays (I have a 360), I am going to shoot something...
EDIT- but of course, IF a create a play option is BACK, but you can't use it in Franchise mode, THEN there will be blood... lol
