The Buccaneers aren’t necessarily a great team, but they are a very good one. The Falcons, meanwhile, are very obviously not.
Tampa Bay’s strengths have been a crisp red zone offense, an above average passing game, and a good defense with some stinkers owing to a sometimes shaky pass defense. They have one of the best run defenses in the league, they get plenty of turnovers, and their offense is good enough on its best days to win games. They’re probably going to run into a buzzsaw in the playoffs, whether that’s the Rams, the Seahawks, the Saints, or the Packers, but they’re still going to get there.
