Walden was effectively tasked from day one with rowing upriver in a cardboard boat, only the NCAA took away one oar (Criner), then the university took away the other (Lester).
Never beat Iowa, but had the game in doubt in the 4th quarter several times, which was far better than the 45-point loss average of his predecessor. And sure, for every ranked win there was an equally stupefying loss -- which was not a unique occurrence among ISU coaches before or after.
Nebraska, never ranked lower than 11th
Oklahoma, ranked every year
Colorado, ranked 6/8 years (and at the height of the McCartney era)
Kansas, who even cracked the rankings and went to a bowl game under Mason
The very beginning of the K-State upward push with Snyder
Oklahoma State with the Sanders/Gundy/Dykes trio (first 2 years)
...and of course, Iowa
If nothing else, at least it was entertaining.
