I won't say they did it intentionally, but I've always felt like MyCareer was set up to be a 1 year mode - especially the next gen version.
If you look at years past, all endorsements were earned in year 1. The mode becomes a series of quick matches after that.
That's no excuse for there not being a FA tho.
This game was definitely rushed to meet the release of the next-gen consoles. Whether 2K put that pressure on themselves, or the parent company, Take Two, did...it's the gamers suffering..
