NFL teams are never without options, which is an especially good feature of the league for some of its teams struggling the most through six weeks.
Those teams can utilize the waiver wire, trade market before the Nov. 2 deadline, sign free agents and shuffle around the depth chart to address problem areas.
Granted, some things are beyond repair. A couple of transactions aren't going to save the dramatic rebuild in Jacksonville. But some teams that could see a significant uptick in performance after slow starts with one or two moves.
Whether it's a team trying to turn things around or a rebuilder that needs to change philosophy to better position for the long term, the following franchises need to make noteworthy roster moves now, not later.
Pittsburgh Steelers: Trade for a WR
An inconsistent start for the Pittsburgh Steelers has featured a bad showing from Ben Roethlisberger during what could be his farewell tour.
Big Ben, barring the team's Week 5 win over a middling Denver Broncos, has looked like a player most teams would bench were he not a modern franchise great. And a ho-hum cast of weapons around him hasn't helped; JuJu Smith-Schuster ranked fourth on the team in receiving with just 129 yards before going down with a season-ending shoulder injury in Week 5.
The team won't keep pace in a stacked AFC North where high-flying offenses have all other teams on at least three wins and Baltimore on five.
In Pittsburgh's 3-3 start to the season, Diontae Johnson leads the receiving offense with 376 yards and three touchdowns. Removing JuJu from the equation means one less safety blanket for a quarterback who desperately needs it.
James Washington, who featured in trade buzz over the summer, isn't the answer. The team shouldn't gun for a Michael Thomas-caliber player, but floating a mid-round pick for a someone like Brandon Aiyuk in San Francisco could provide immediate help and boost the franchise's long-term outlook.
Atlanta Falcons: Bench Mike Davis and Fabian Moreau
After awkwardly straddling the line between rebuild and contention this offseason, the Atlanta Falcons look like they don't stand much of a chance in the high-flying NFC South.
In the team's 2-3 start, there have been key underperformers on both sides of the ball.
On offense, the team signed free-agent running back Mike Davis in the offseason, and he has responded with 204 yards on a 3.3 per-carry average over five games. He has easily been outplayed by Cordarrelle Patterson, a 30-year-old former wideout who has 173 yards on a 4.2 per-carry average and is also second on the team in receiving with 295 yards and four scores.
And on defense, cornerback Fabian Moreau has played 91 percent of the defense's snaps over five games, earning a 44.9 Pro Football Focus grade (the "replaceable" player category starts at 59.0), allowing 20 catches on 28 targets.
