I have seen a TO after another a huge cuantity of times. I have a teory of how it works:
Imagine the GE gives you a cumulative penalization on handling for each possesion. When you reach 4-6 posessions, a TO becomes more probable. Imagine this penalization works for the two teams and rise exponencially. It would be easy as it hapens that the two teams find this penalization too hight to keep the ball nearly at the same time. In the other hand, if you have a hight hadling in all your players, perhaps you can live with this penalization one or two posesions more and reiniciate it a bit later, having less TO than the other team at the end of the match.
I know this system is not very realistic, but perhaps it is easy to programe and developers implemented it like that when they created the GE. This could explain the usual TO + TO that we can see many times. Someone thinks it could be possible?
Sorrry for my english, i hope i have get understood.
