In Madden 13 there is no player potential in Connected Careers. However, in Madden 12 it is one of the more limiting parts of Franchise Mode. If you have wanted to know how to change a player’s potential rating from an ‘F’ to an ‘A’ this is how you do it in your Franchise Mode.
It is also important for you to know that the Potential Rating is dependent on the Overall Rating as you edit. It is easy to calculate a player’s potential when it comes to this:
90-99 OVR = A
80-89 OVR = B
70-79 OVR = C
60-69 OVR = D
59> OVR = F
