Leaving out a bunch of pre Post-War coaches:
Gardner, Tex, Fitzsimmons, Hartman, Huggy, Frank - above average
Altman, Oscar -- average
Wooly, Asbury - below average
If Oscar is allowed to stick around another year and things don't drastically change, you could make an argument for below average, especially when you consider where the program would be at his departure, which would be the lowest point since Asbury's firing.
