question on nfl blitz 20-03

i am playing the exibition mode and i want to use my user name and pin but i dont wanna use the created player i made or the 1 they give to u if you create a pin.  the created player is never good and i cant win but when i dont use him and just use a normal team on quick play i do fine.  how can i play and earn points and keep stats but not use the created player?  thanks
