The teams in Dallas's division all have winning records except Philly which is 1 game below .500. I don't see where that qualifies as a weak schedule. The team with the weakest schedule is the Texans, who are lucky to be in the worst division in the league.
I think the NFL should award playoff spots based on w/L records not just on division standings, that way stinkers with 8-8 records wouldn't advance over teams with better records in better divisions.
Because the teams they have played ...and beaten, this year had an average record of 5-11 last year. Those teams MAY have a better record than that THIS year but they also would have a weaker schedule this year based on their record last year.
NFL strives for parity plus we all know Jerry Jones is a loser.
