PULLMAN – Ernie Kent never got to coach in the basketball Taj Mahal that he helped erect. When he does for the first time Sunday, he will do so as an intruder. Totally modern, the 12,364-seat, $227 million Matthew M. Knight Arena is an homage to “new money” and the envy of most professional teams. It opened the year after Kent was fired by the University of Oregon after two bad seasons but would likely not have been built without the five NCAA tournament appearances and two Elite Eights he achieved during his time in Eugene.
