I'm the least worried about the Saints. Their window is closing fast, and I could not be happier. Can't stand Ryan and the Falcons, but if they plug some holes, they are an 8 and 8 team. Tampa has the opportunity to be vastly improved going forward. I believe they take Winston, and I have no doubt he will quickly become a franchise QB. If not for the off the field stuff, everyone would be saying the same things they said about Luck just a few years ago.
I honestly believe the Panthers will win the NFC South for the next two years. After that, the Bucs will be our closest competition for the division. Go Panthers!
