every spot should be able to play if they were to add this. I never thought that playing Goalie would be any fun but its intense. Playing Oline is really fun to in superstar mode. You have the ups for setuping up big plays and then you also have the downs for missing a key block or letting up a sack.
I would also come down to who would play QB. What if no one wanted to play QB? It could led to alot of problems because the current setup is you call for the ball and it comes or your qb makes horrible choices and it ruins your superstar(or online if 11v11 happens) exp.
That being said I might not even play it because I only play with my friends. Not that many of them would be interested in doing an 11v11 because they like control.
On the other hand, it would be nice to play francise at home online instead of having to meet up when we can and play it at one persons house
....Its also time consuming because one person has to wait for another to finish his game or seting up his players before the other guy can.
All in all, Online francise would be gold. Where as 11v11 would be silver. Offline francise if fixed would be tied for silver or it would land bronze lol.
