  Among the sports fans beliefs about "hot hands" and "winning streaks" are
widely spread, while the scientific debate about these effects is still
ongoing. Recently in a paper by P. Ferreira [Physica A 500: 92-96] detrended
fluctuation analysis was applied to the NBA teams' win records. It was shown
that 28 considered NBA teams exhibit persistence in the win record time series.
In this paper we take the same data set and compare the obtained results
against various random models. We find that the empirical results are
consistent with the results obtained from various simple random models.
