My understanding, this was a case of Coach Rach truly stepping down for "Personal" reasons. He has so much happening in his personal life, he didn't feel he could dedicate himself at this time. I heard things like: Has a young child (2 years old or so), has another one on the way any day now, and has had multiple surgeries over the years, all of these played a factor in his decision to step down.
This really stinks! Just another Black Eye for WR! Not sure where we will go from here, will be an interesting couple of weeks / months. Our schedule is front loaded with really solid Teams, whoever is taking over will have their hands full.
