It is no shock to anyone that the Tampa Bay Buccaneers will be the biggest competitor to the Saints in the NFC South this year. They will also be the biggest threat to beat them out to win the division and take the Saints streak away.
The biggest fact that separates the two teams is team chemistry. I would expect the Buccaneers to at least lose a couple of their first big games just simply due to the fact that they have a new quarterback and tight end.
Tom Brady is still getting to know everyone and the other way around. It has to be hard coming from playing in the same offense for over a decade. The Saints, on the other hand, brought back most of their starting lineup.
The most important being their future Hall of Fame quarterback Drew Brees.
The Saints have been on a tremendous run over the last three years. The team has separated themselves as superior from everyone else in the division. This year, they will in their fourth consecutive NFC South divisional title because of these reasons.
