It appears the arena was filling up as the end of the season was coming to an end.

Cleveland 19069
Toronto 19382
Detroit 18729
LA Lakers 20190
Indiana 16646
Orlando 16887
San Antonio 18729
Charlotte 17697
Detroit 18214
Golden State 14066

I think a big reason why those attendance numbers improved is because they drastically cut down the number of 7:10 starts late in the season.
