This is nothing new really. In OOTP4 guys would increase talent when doing horrible and drop after a career year as well.
I think alot of the problem is we have pre-concieved notions on what good players look like in OOTP4, but OOTP5 works differantly when it comes to ratings and talents making us think someone isnt as good when looking at their talent and ratings, but the stats come out looking pretty good.
Im under a current theory that it is causing some real wild things to happen in conversions as OOTP5 sees version 4 leagues as way overtalented and rated with the version 5 system.
Its late

, just a

theory when it comes to the ratings/talent issues coming up.
