Eastern Teams Lately

A month or so ago, many of the mid-tier Eastern Conference teams were maybe 4-6 games behind the similarly placed Western Conference teams, but that seems to be changing towards parity more. What might this mean? -> teams are getting better and players are improving as the season goes on. Kings may have a tougher time than some may expect too; they have lost 3 in a row once so far this season, and that stat may increment one tomorrow.
