Four Downs

In what could be the NFL's most unpredictable division, the Bills need pass-blockers, while the Jets and Dolphins need pass-rushers. The Patriots? They need pass-catchers ... assuming they know what they're doing with the man passing the ball.

The Ravens and Bengals need blockers, while the Browns need help in the secondary. As for the Steelers, it's time to accept that they'll probably never get 16 games of a healthy Ben Roethlisberger again.

Don't look now, but the Indianapolis Colts have a shockingly complete roster, leaving us struggling to identify any significant needs, save a possible upgrade on their interior offensive line. Elsewhere in the division, the Texans and Titans need pass-rushers, while Jacksonville needs cornerbacks.

The Broncos made a lot of moves this season that put them in win-now mode, but what if Drew Lock's not up to the task? Meanwhile, the Chiefs and Raiders need help putting other team's quarterbacks down, and the Chargers need help keeping their new quarterback upright.

While the Eagles are thin at linebacker, their division rivals in Dallas, New York, and Washington all need players who can catch the football.

If you have ever caught a football, please send your resume to Green Bay. Elsewhere, the Bears and Vikings need help in the trenches, while Detroit needs to shore up the middle of their defense.

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.

Four Downs wraps up with a look at the AFC West, where the Chiefs and Raiders need linebackers, the Broncos need to keep Drew Lock upright, and the Chargers sail down uncharted Rivers.

Quarterback question marks abound in this division, but even some of those teams with unanswered questions have bigger immediate concerns.
