No doubt it happens at times, I suspect recruits talk about that a lot more than it really matters though.
At times, it comes down to what effective is a coin toss. The kid doesn't really know why he ever so slightly prefers X over Y. If both offer a good path to the NFL, either choice is fine, all of them are good choices. When asked to explain, they often say "I just had a great connection with the coaches there.".
And yes, at times that will be the deciding factor. If you are an elite running back, you have 5-6-7 possible choices, all of them great choices. If one program has an obvious SLOT for you, go there, and say you have a great connection with the RB coach.
I am thinking about Knowshon Moreno, a good college back, who was red shirted his FR year. He didn't make a good choice, IMHO, neither did Justin Fields.
Maybe Moreno did make a good choice, he only played two years in college, so he reduced his risks.
