Really? There's an example out there where a player says they don't want someone? That's hard to believe. If my coach asked my what I thought about a recruit, I'd have a hard time giving a thumbs-down, even if I thought that.
I know when I was playing football we hosted a running back from Iowa City (can't remember his name, but was pretty highly recruited) and after his visit the players hosting him told Coach Mac we didn't want him on the team so we quit recruiting him and I believe he ended up at Arizona State. He was a total DB on his visit.
