I'm not sure that this was a good move by Cal. If you tell a recruit/family that you are going to do something then you have to do it, regardless of how well it works (which is why most coaches don't promise anything to recruits). Also, if a recruit/family calls then you have to respond, even if you don't really want the player. Burning bridges is dumb because you never know when someone that you don't like/want is going to be the point for a recruit that you do want. If you intend to keep recruiting players then you must do whatever you can to keep open good communication lines.
