Currently you can see the overall progression for a player.
I would like to see the progression for the individual attributes as well.
Ex:
My QB progressed in Training Camp.
His accuracy was +5/+5, and scrambling was -10/-10, but because I value accuracy much more than scrambling, his overall progression was +3/+3.
Or maybe as he's getting older I can see he's getting slower, but more accurate or disciplined.
