Any discussion on KD needs to look at Akron KD vs KD now.
KD built Akron's program with four-year players. His staff would find diamonds in the rough and develop them into really good players. Romeo Travis, Dru Joyce, Jeremiah Wood, Isaiah Johnson, Nikola Cvetinovic, Steve McNees, the McKnight brothers, etc - none of them were highly recruited out of HS.
And they were so good at this that they reached the MAC Championship in 9 out of 11 years (and 7 straight) while reaching The Dance three times. "20 wins and that's it" is utter nonsense. He was a great coach here.
But the college basketball landscape has changed over the last few years. With the transfer portal filled up every summer, 4-year players at mid-majors are becoming less and less common. NIL money is drawing players away from mid-majors even more now. His intense style probably isn't well-suited for an atmosphere where you have to re-recruit your entire roster every year either.
I think, like many great coaches before him, the game has evolved beyond him. That doesn't mean he wasn't a great coach for us - he was - he revived Akron basketball.
It's possible to be appreciative of his time here and wish him the best while simultaneously being excited for what Groce is building.
