The haters keep invoking Lute, Ralph and Mr. Davis. (Remember that Raveling was basically run out of town by the fan base at the time, mostly due to criticism of his outside interests and his skin color.)
Ralph had peaked and was trending down. Mr. Davis, after starting at a high level was trending down except for the last season (it was announced it would be his last season before it started). Lute peaked in the middle of his years at Iowa; I remember many wanting to run Lute out of town due to losing to Wichita St in the tournament (by trying to stall the entire second half away).
It seems the farther back in history our former coaches get, the greater they were.
Your argument doesn't jibe with the facts. Lute had an almost identical record his last year as his Final Four year; 23-10 vs 21-10. Ralph Miller won the Big 10 championship, with an undefeated record and was 20-5. He was at the top of his game!... and then he left. Mr. Davis made the Sweet 16 his final year. All three of those were great coaches, the first two among the greatest. Mr. Davis could coach, but not recruit.
So yes, the bar is high....I would argue that the Alford/Lick years are the anomaly in Hawkeye BBall history, not the norm. And remember the NCAA wide open field of 64, now 68 is relatively new. Fran has had six years, this should have been his peak year....because of the seniors. Are the expectations so low after Alfraud and Lick that mediocrity is now accepted? Not a hater, I want Iowa to be the best......why don't you?
