I do not understand what is meant by Key Arena not being up to NBS Standards. I guess the 1995 upgrade to then Seattle Center Coliseum does not count for anything.
KeyArena is the first publicly financed arena fully supported by earned income from the building. Its seating capacity for basketball games is 17,098, ice hockey games and ice shows 15,177, end-stage concerts 16,641, and center-stage concerts and boxing 17,459. Risers hold 7,440 on the upper level and up to 7,741 on the lower level, with luxury suites adding another 1,160 seats.
The renovation cost the city of Seattle $74.5 million, and the Seattle SuperSonics approximately $21 million.
The first regular season game that the Seattle SuperSonics played in the rebuilt arena was on November 4, 1995, against the Los Angeles Lakers.
So what do they mean by not up to NBA Standards
