Has anyone played through a career long enough to see their ratings regress when they get 35+ years old? Do they regress this year?
I saw a video where a guy simmed his entire career and your agent calls you in the off season at age 34 and lets you know that you are about to have abilities begin to decline. He got his choice of a set of skills to keep intact and apparently you have to accept that the others will slowly decline from that point.
Because he simmed the entire career you don't know if you can slow the decline with the training mode during the season or not, but I suspect that if you have skill sets similar to the ones you choose to focus on those will decline slower if you train.
