Football Outsiders' look at the greatest teams over the NFL's first 100 years kicks off! Here's a look at the methodology behind our Dynasty Rankings and a list of all 56 teams that we'll be covering over the next three weeks.

While the Falcons need running backs, the Saints and Panthers need help in the secondary. The Buccaneers? They need a Plan B in case Tom Brady is anything less than Tom Brady.

With free agency and the draft complete, we look at the biggest remaining need on each NFL roster. Starting out west, the Cardinals and 49ers need help in the secondary, the Seahawks need edge rushers, and the Rams need to figure out what they're doing at offensive line. We also look at each team's notable undrafted free agents.

The annual review of the best values in free agency weighs in on Tom Brady versus Philip Rivers, Robby Anderson versus Breshad Perriman, and ex-Patriots versus post-New England reality.

Jameis Winston became the first quarterback to throw 30 interceptions in a season in over three decades. Surely some of that must have been bad luck, right? As a matter of fact, no, it was not. We explore Winston's mind-boggling season, and look at the quarterbacks with the best and worst luck in 2019.

This month: a bunch of players get drafted, the draft fallout gets discussed for a day or two, and then we all go back to our binge-watching and meme debates.

It was a year of extreme highs and extreme lows in NFL draft grades. Dallas came out way ahead of everyone else, thanks in part to their selection of Oklahoma wide receiver CeeDee Lamb. Meanwhile Green Bay finished last by a very, very, very wide margin.

In many ways, NFL coaches are more aggressive than they used to be. Going into halftime, though, they still frequently run out the clock when they should be trying to score -- unless, of course, the backup quarterback is in the game.

What makes a good run a good run? Guest columnist Caio Brighenti uses visualized data to show that more often than not, it has more to do with the blocking at the point of attack than with who is carrying the ball.

The Raiders and Broncos go all in on offensive weapons. The Eagles pair Jalen Hurts with Carson Wentz. The Packers ... we have no idea what the Packers are doing.
