Brunk & Howard both had plenty of other options too. Not just between Purdue & Butler.
I think everyone should build a yurt, buy some good tobacco, go in, shut the door, light the pipe, close their eyes, and picture themselves as the Father (or Mother) of a good player who has scholarships offers from ten or so good schools (PU, IU, Xavier, Butler, etc). Consider the person your son is. Consider he is probably not going to the NBA. Consider that he is (or is not) a good student wanting to major in a real major. Consider his social likes ... introvert/extrovert. Wants a big school, doesn't like big schools. Wants to be the star, or he doesn't want the limelight.
Nothing here has much to do with how good a player he is (other than not good enough to go on) ... it has to do with your son's personal happiness and future success.
At one time, my son was recruited heavily by Bellarmine. He ended up going D1, but he was a very low D1. ALL Bellarmine talked with him about was their incredible network of alumnae in business and how guaranteed a great job was for him when he graduated. It was VERY enticing to me as a Dad.
Now, each of us can do the same exercise, only this time our son is Scruggs and he has an offer from Kansas, as well as every top 50 schools with six states of Indiana. How would you look at this as his Dad?
Without knowing what parents, players, advisors, say in the privacy of their homes. To think that we "lost" someone to Butler or Xavier is assuming the school did something to sway their decision. We all know what "assume" means.
