Thanks...I totally understand where you're coming from. Last year, my first time applying, I really thought I understood what the whole match/fit conversation was about. I had an interest and SOME background in depression and imaging work, and had a big interest in personality research without any background in it, but I thought I could make a story for why I was the right candidate for all my POIs. At the time I remember thinking that I wrote a pretty decent 'story' in my SoP tying my interests, background and POI's interest together but now I realize I was being completely naive and my SoP's were vague, and really that the fit wasn't there especially when you consider that there are 10s of others applying to the same professor that may have done a few years in EXACTLY what the POI studies. I guess, for me, the difference this time around is I tried to find POIs who research matches my background almost exactly or a way I could really contribute to their research with my research background. I feel like I'm rambling, so I hope this made sense!
