Four Downs

Four Downs wraps up with a look at the AFC West. The Chiefs need a half-dozen new defensive starters, the Broncos and Chargers need to revamp their offensive lines, and the Raiders need to turn the Khalil Mack trade into the next Khalil Mack.

Everyone has passing needs down south -- the Jaguars need someone to throw them, the Colts need someone to catch them, the Titans need someone to pressure them, and the Texans need someone to cover them.

The Ravens have committed to Lamar Jackson at quarterback -- now they need to commit to getting him some better receivers. Meanwhile, the Bengals need a tight end, the Browns need a wideout, and the Steelers need defensive backs.

The Bills and Dolphins need offensive line help, the Jets hunt for something they've been missing since John Abraham, and the Patriots try to reshape their receiver depth chart.

There's a lot we don't know about the Rams, but we know they need pass-rushers. Elsewhere, the Cardinals need blockers, the 49ers need defensive backs, and the Seahawks -- shockingly -- don't need help on the offensive line.

The Falcons and Panthers both require serious help along the defensive front, whereas the Buccaneers and Saints have still not filled their biggest post-draft holes from last year.

The Bears could suffer some major losses in the secondary that would make it hard to repeat as the league's best defense. Elsewhere, the Lions need pass-rushers, the Packers need pass-catchers, and the Vikings need pass-blockers.

Our look at the biggest holes on each NFL roster begins in the east, where New York and Washington need passers, while Dallas and Philadelphia need coverage help.

There's a serious need for defensive help in Kansas City, Los Angeles, and Oakland. In Denver, meanwhile, the Broncos must determine whether or not Case Keenum can really be a long-term solution at quarterback.

The Jaguars and Titans both won playoff games last year. Are the days of this division being the NFL's laughingstock over? Maybe not -- all four clubs failed to address critical weaknesses in the draft.
