Even if they lose 3 of the next 4 or even all 4 games there is no reason the Panthers shouldn't win out (or come very close) the rest of the year after Philly despite the defensive issues IMO.
Worst case: 9-6-1
Best case: 11-4-1 (assumes losses to GB & Philly)
I am predicting 10-5-1 and NFC South champs again
Its all good...2nd half of the sched will save the season!
