Yeah, I think the least controversial takeaway is that you can afford to have a large protein shake immediately after workout. I personally don't think you need to. But this study and some others indicate that muscle responds best to protein consumption when it's in some post-exercise state (but it's unclear if that state is 30 minutes or 3 hours or longer etc). I'd say it's more important to focus on your overall daily consumption rather than the timing of it
