If Ekeler were to leave I wouldn't mind seeing Bill Busch come in, he's a proven coach that would do a great job and he lives in Nebraska. Not only has Bill coached special teams but many positions on the defensive including coordinator, he has a proven record. I will say one of Matt Rhule's biggest mistakes was when he was hired he did not retain Busch who was on the previous staff, Matt made the big mistake, he chose that former ST coach Foley? what a mess that was. By the way Busch is available and probably would love to coach again, he has a wonderful football mind and is a great recruiter, he would be a plus for the Nebraska football team. I just think Matt is too hard headed sometimes and needs direction when it comes to hiring the right coaches.
