I was able to fix it last night. Turns out that on Steam, even though I was online and connected to the internet, I was set as offline in the Friends section. Go to Friends > Online in the top menu. When you do that and restart 2k15, you will be able to see your friends in the locker room and MyCareeer > MyPark.
Both of you should make sure that you're set to Online. Let me know if this fixes it for you.
