KY recruited quite a few guys who ended up going somewhere else. I think you’re implying that he was selective about who he recruited based on being able to mesh with others already on the team. I think he went after a bunch of guys with talent, and several ended up wanting to play for him and were also okay with the cultural aspects of byu.
It’s hard to say he was all that concerned about their ability to mesh when he hasn’t coached a single player on the roster yet.
