defencive/ attacking potential?

i just had a thought about how a players potential could be a bit more specific. it could be devided into defencive or attacking. the best way i can explain this is as it is if you have a full back with -9/-10 potential they will basically turn out to be an all round great player. with my idea they could have say a -10 as attacking potential and -8 defencive potential and turn out to be a great attacking full back but not so good defencively. or if the numbers were the opposite way around they would be a solid full back who doesnt get foward too much. what do you think?

Nothing wrong with current system. Nothing at all.

Don't you just have to look at his attributes? What he's best at now is probably the same things that he'll be best at when he reaches his potential, unless he's trained in a specific way.
