They should have changed noticeably in two seasons though. I'd just start taking the occasional photo of the stats screen to compare them side by side - I took some early in my career and it's a good way to see the real progress that I've made.
good advice matt...will take a photo and compare the results after one year to see if anything has changed..
btw, when creating new career player, how much difference would it make if the strength bar is full (what effect will it have on players mentality)..
any clues!!!
