"the 3 worst years in the history of the program"
is not the same as,
the worst 3 year period in the history of the program.
Even when considering the worst three year period, KA's 27-68 record 0.284, is still better than the 16-59 0.213 Tigers from 65-66 to 67-68; and better than Vanatta's last 3 years of 19-54, 0.260. winning only 3 games each of his last two seasons.
So just move on, because you are 100% statistically factually wrong on the bottom line of wins and losses.
