You're not giving 17 year olds enough credit. They're involved in a process, and that process has rules. Rules that all the other commits can handle. Brown knew these rules, and broke them. This either means he didn't care about the consequences (he was OK with losing his spot in our class) or he has a problem following rules
Since I'm also sure Brown's parents knew these rules, I'd guess this means he just like Oregon better than Michigan. This should not reflect poorly on Hoke, he's just doing his job.
What would you rather Hoke do? Let these kids visit anywhere and then scramble when guys de-commit?
