Plenty of good points pro and con brought up in this thread.
I was in school and a young alum from 1989-94, and I only missed one home game (KU in 1990) - as I was out of town (FSU @ Miami game with my brother). The 1989 team was exciting and showed promise for the future, but 1990-4 flat out sucked even with the Upset wins over OU in 1990, Nebraska in 1992 and K-State in 1993. He definitely didn't have the fan / admin support that we had in the 70s or have now.
However, I do not think he would have succeeded with today's support either. To me, the biggest issue with Walden as a HC was that like Rhoads, he could put together a solid Xs and Os game plan for a single game, but he had no concept of how to build a PROGRAM like Earle Bruce or Matt Campbell for the long haul. Just my opinion. I was glad to see him go as HC, but I have always wished him the best in life and as a human being. No issues with him in that department.
