I actually agree with Jon Laurent here. I don't know at all why, but just speaking from my own experience, having drafted and trained a player currently on my roster (Cedrick Pagan) who had that starting combination of 1 handling and 7 driving, I know that handling will at least initially increase faster than driving. I have not single-position trained handling and I've done a lot of 1v1, but right now Pagan is still 10/15 HA/DR. So as you can see, handling has increased faster than driving, which would seem to rule out the possibility of a 13/20 build.
