Four of the next six games are vs. the top two teams in each conference (Warriors, Spurs, Cavs, Bulls). The other two games are on the road, vs. an underperforming playoff team from last year in the Pelicans, and a decent Charlotte team that's currently 10-8 (that game will be on the second half of back-to-back after playing Golden State.)
Going 2-4 over these next six could be a decent achievement, especially if Smart is out the entire time.
