The bigger difference now is the schedule is substantially tougher. Road games at Seattle, San Diego are probably losses, and at NO is always tough.
And throw in Arizona, Denver, San Fran, Philly for your home games instead of Buffalo, NO, Miami, Tampa Bay.
The schedule is much easier. AFC East was tougher than AFC West especially due to at Patriots. Miami/Buffalo are comparable to SD and KC. We can easily beat KC, SD, Oak and Denver (home). 4-0 for Detroit is most likely.
NFC West offenses are junk. Rams (offense) and 49ers are a mess. Cards lost Bowles and Cromartie. Seattle lost Maxwell, Unger. We can easily go 3-1 against NFC West.
Philly and at Saints won't be easy but Lions are good enough to split. Saints defense is a mess still and they lost Graham.
NFC North 5-1 again though Vikings are tougher. Packers have CB, ILB, Dline issues and were very healthy last year. I don't see them being super healthy like they were.
11-13 wins is most likely for Detroit with their schedule.
