I thought Mumme was a good influence in the offense. Some nice two back sets, good combo of the vertical and horizontal passing games.
That said, we had June, Morrison, Mumme, Chang, Phillips, and Suan on the offensive side. If I were to look at this from a more positive perspective, someone had to go so that we could spend money on some coaches who actually know certain positions. Chang at RB doesn't make much sense, and Mumme and Morrison both coach QBs.
I kind of thought Morrison might be the one to leave, but my hope is that this opens the door to be able to bring in a good recruiting coach at LB or ST.
