I think this is a really good development, both for Bolles and Jackson (for basketball.) I do not think that it automatically means that either of them are not going to eventually end up back at the Y. From a practical life standpoint, and a gospel standpoint, the best decisions are almost always made when due diligence is performed. Even the scriptures say to "Study it out in your mind." Let them go see what is out there, get info, pray about it, and make a sure decision they can truly commit to.
In the long run it is better for the team to have players who look elsewhere and then decide to commit to BYU and give it 107%, than to have players who commit and even play, then decide to transfer later (Leavitt and Kearsley come to mind.)
They are going about it the right way. Communicating with BYU coaches as to what their intentions are, talking to other coaches and teams, making visits, etc., having all the info they need then making a decision and having no regrets that maybe had they done something differently they would be happy elsewhere.
If you are worried that the girl you are dating is going to fall for some other dude just because she visits his apartment, you should be doing more to work on yourself and remember you cannot, and should not, control others.
Certainly, if I was a potential player and cared what the fans think, I certainly would be turned off by those who wrote me off just for being forthright about my intentions.
