From what I've gathered from interviews he had every intention of taking a year off and spending time with family and the such. Shortly thereafter he realized he can't just sit at home and needed to be coaching a team. I'm sure he had a short list of guys he had for position coaches and the such, but there's so many dynamics to football, who knows if some guys wanted to stay in the pros or retire or had no interest in moving to Nebraska. While the Raiola hire is a bit of a headscratcher, it does provide continuity to an OL that hasn't seen much of that. Rhule must see something we don't and we just have to trust him on that judgement. Hopefully the O-line is improved but only time will tell.
