Can X-Factor Ability to be acquired?

[niles08]

These questions revolve around franchise mode,

1.) can a player I draft be of X-Factor ability? Will I know he is when I draft him?

2.) Can one of my current players acquire an X-Factor? Say Baker Mayfield has a great year, can he acquire a certain X-Factor based on what he excelled in? Another way to look at this is how development worked last year, where players would go up or down in development during great or horrible seasons, does X Factor work the same way?
