Logically, when comparing the schedules between the Pats and the other three AFC East teams, the common games shared by those teams 12) have to cancel, and the two against each other shouldn't count - which means that, based on the previous season, the Pats will ALWAYS have the tougher schedule, since the two uncommon opponent games put the Pats against the two other AFC division winners. THe only reason the Patriots have an "easier" schedule than, say, the Jets, is because the Jets play the Patriots twice, while the Patriots play the Jets twice. Both teams will play four against Miami and Buffalo, four against the AFC West, and four against the NFC South. (Leaving the Pats with Houston and Pittsburgh, while the Jets get who? Jacksonville and Cleveland?)
Also, the NFC South > the NFC West and probably the NFC North, as well. Atlanta is the current class of the NFC, the Panthers have been to the SB with essentially the same team, the Saints are always a tough out, and the Bucs were much-improved last year (should have beaten Denver).
And the AFC West is a stacked division - probably the best division int eh AFC. So I find this analysis lacking. Sorely.
