Anae - Not a great recruiter or people person in general. Players don't like him and neither does the media and boosters.
Bronco - Wasn't great with fans, boosters, media as well.
Sitake - No discipline in his program. Organizational mess.
Whittingham - Can't get a good, consistent offense on the field for the life of him
Ken M - Too closely tied to the triple option and won't ever give it up

Unfortunately BYU has a small HC coaching pool and each guy has his issues.
