These sliders are for 2K11 ONLY. I know that 2K14 played much differently from 2K11 and the sliders I had were very different. So I would not suggest using these in 15. I have no plans to continue developing sliders or rosters for games any longer, as I am a 360 owner and will not be purchasing a next-gen system. So you might want to check and see if other contributors here have provided 2K15 sliders.
It's taken me a LONG time to get the sliders right for 2K11 - but this game is a keeper for me, and I'm going to play it until the disc wears out. It was well worth my time to work on these for so long.
