The Philadelphia 76ers is one of the surprise teams this season and they're currently on top of the Atlantic division.. They're playing well but I believe they will not be able to keep this up because as good as their record may seem, they really haven't been tested yet.. Their schedule has been kind this early and they haven'y really beaten the top teams, and come February, the real test for them begins.
Comparing the Sixers and the Celtics next 15 games:
PHI - chi, mia, atl, lal, sas, lac, cle, cha, orl, dal, min, mem, hou, det, okc
BOS - cle, tor, nyk, mem, cha, lal, tor, chi, det, chi, det, dal, okc, cle, mil
We're 5 1/2 games behind but barring any more injuries, I believe we'd take over the Atlantic by end of Feb. or first week of march (when we play them in mar.7)..
