How do you make trades in 2K15?

I'm trying to make the Bucks-Pistons trade a few days ago, and can't find what screen to do it from, and make it save so I can use it. Anyone know where and how to do it? It was easy to do in 2K14. I thought 2K would have updated the roster by now.

It should be same as in 2k14. Just click on player and menu with trade option should pop up.

Indeed, basically the same method as before, when viewing the rosters.

Still can't find what you're talking about. Went into roster viewer, clicked on a bunch of options, which shows player attributes, career stats, etc.. no trade options. Can some one give me a step by step? Would appreciate it. These screens on 2K15, are more confusing to me.
