Although not as bad as the 2008 version that finished 0-16, Calvin Johnson (81) and the Lions have taken a huge tumble after last year's 11-5 mark. Blame that on the lack of a running game, a poor offensive line and a defense that hasn't recovered from the offseason departure of defensive tackle Ndamukong Suh. Oh, and the refs, of course!

San Francisco (1-3): D
A coaching change hasn’t resulted in improvement for quarterback Colin Kaepernick. He has thrown two touchdown passes with five interceptions for the NFL’s lowest-scoring offense (12 points a game).

New Orleans (1-3): D
Drew Brees gutted his way through a Week 4 overtime win over Dallas. But with a shoulder injury still affecting the quarterback’s play and a youth movement underway on defense, more dark days may soon be ahead for New Orleans.

Tampa Bay (1-3): D
Though the Buccaneers have made progress after finishing with the NFL’s worst record (2-14) last season, Tampa Bay will continue to flounder as long as Jameis Winston keeps making the turnovers and mistakes common for rookie starting quarterbacks.

Chicago (1-3): D
What was widely considered the NFL’s worst team got into the win column with the return of Jay Cutler and a Week 4 upset of Oakland. The struggles are likely to resume as the Bears continue to overhaul the roster under new general manager Ryan Pace and head coach John Fox.

Philadelphia (1-3): D
The massive offseason personnel changes made by Eagles head coach Chip Kelly on offense have yet to pay dividends. Such failings are putting too much stress on a defense that has improved from 2014.

Kansas City (1-3): D
Andy Reid's Chiefs are in the AFC West basement after a brutal stretch of games against three undefeated teams (Denver, Green Bay and Cincinnati). The offensive line must do a better job protecting quarterback Alex Smith, who has gotten sacked an NFL-high 18 times.

Houston (1-3): D
The excitement surrounding the Texans following their training camp 'Hard Knocks' appearance quickly dissipated. Ryan Mallett and Brian Hoyer have both flopped trying to quarterback an offense hit with injuries to star running back Arian Foster (23) and the line.
Miami (1-3): D
The Dolphins are off to such a disappointing start that head coach Joe Philbin was fired less than 10 months after being signed to a contract extension. Interim replacement Dan Campbell now needs to kick-start QB Ryan Tannehill and an underachieving roster.

Jacksonville (1-3): D
The chance to take first place in the AFC South was squandered when kicker Jason Myers and the Jaguars couldn’t beat the Andrew Luck-less Indianapolis Colts in Week 4. Jacksonville won’t be contending again this season unless the NFL's 31st-ranked scoring offense (15.5-point average) shows improvement.
Baltimore (1-3): D
Lousy pass defense following the season-ending Achilles injury suffered by outside linebacker Terrell Suggs in Week 1 against Denver was the main reason for the first 0-3 start in franchise history. Now Steve Smith (89) is hurt, too.
Ron Chenoy-USA TODAY Sports
Cleveland (1-3): D
Josh McCown's Browns have lost to three teams that didn’t make the playoffs last season. The rough part of the schedule is yet to come with games against Denver, Arizona, Seattle and every division rival twice.
Tennessee (1-2): C-
Marcus Mariota shows all the earmarks of being the franchise quarterback Tennessee long lacked. But the Titans are leaky on the offensive line and surrendered an average of 31 points in back-to-back losses against Cleveland and Indianapolis.

Seattle (2-2): C
Strong safety Kam Chancellor's return following an unsuccessful contract holdout has provided a defensive boost, but the offensive line is a train wreck that could get quarterback Russell Wilson hurt if the blocking doesn't improve.

St. Louis (2-2): C
With victories over NFC West rivals Seattle and Arizona, the Rams have shown the ability to win the division. The emergence of rookie running back Todd Gurley could be the element that ends St. Louis’ 11-year playoff drought.

Minnesota (2-2): C
A 23-20 loss to Denver in Week 4 shows the Vikings still have a bit to go before becoming an upper-tier team. But the arrow continues to point up for one of the NFL’s youngest and most talented rosters, especially with Adrian Peterson back.
USA TODAY Sports
Washington (2-2): C
Kirk Cousins might not be the long-term answer at quarterback, but the run-heavy philosophy adopted by head coach Jay Gruden in the post-Robert Griffin III era has led to offensive improvement.
Brad Penner-USA TODAY Sports
New York Giants (2-2): C
Despite being beleaguered by injuries once again, what may be the NFL’s most overachieving team could actually be 4-0 if Eli Manning and the Giants wouldn’t have suffered fourth-quarter collapses in Weeks 1 and 2 to Dallas and Atlanta.

Dallas (2-2): C
The Cowboys haven't been able to overcome injuries suffered by Tony Romo (clavicle) and Dez Bryant (pictured, foot). Dallas is 0-2 since losing both parts of their quarterback/wide receiver combination, with no relief in sight entering Sunday’s game against New England.
Ronald Martinez/Getty Images
San Diego (2-2): C
Injuries have wreaked havoc with San Diego’s offense, but quarterback Philip Rivers (17) is keeping the Chargers above water. Tight end Antonio Gates’ return from a PED suspension should provide an immediate boost starting with Monday night’s game against Pittsburgh.
Jake Roth-USA TODAY SportsJake Roth
Oakland (2-2): C
New coach Jack Del Rio hasn’t needed long to make an impact. The Raiders are off to their best start since 2011 with wide receiver Amari Cooper emerging as the early leader in the NFL Offensive Rookie of the Year race.

Indianapolis (2-2): C
Andrew Luck's Colts hardly show the makings of being the AFC front-runners for Super Bowl 50 as installed by oddsmakers during the preseason. But close victories the past two weeks are good enough to put Indianapolis back atop the decrepit AFC South.
Christopher Hanewinckel-USA TODAChristopher Hanewinckel
Pittsburgh (2-2): C
Ben Roethlisberger’s leg injury, drug suspensions for two key offensive players (running back Le’Veon Bell and wide receiver Martavis Bryant) and lousy kicking by Josh Scobee have the Steelers out of sorts.
Jeff Curry/USA TODAY Sports
Buffalo (2-2): C
Rex Ryan as head coach is a double-edged sword. The Bills exhibit great passion but also lead the NFL in penalties (47 for 428 yards), exemplifying a lack of discipline that played a big part in both of Buffalo’s losses.

New York Jets (3-1): B
Opponents have the NFL’s lowest quarterback rating (62.3) when facing New York’s aggressive defense. RB Chris Ivory and the offense aren't too shabby either. Brandon Marshall is the first Jets player with three straight 100-yard receiving games since 1988.

Arizona (3-1): B
Arizona’s high-powered offense was slowed in last Sunday’s 24-22 loss to St. Louis, but Carson Palmer's Cardinals still lead the NFL in touchdowns (18) and point differential (plus-75) while sitting atop the NFC West.
Matt Kartozian/USA TODAY Sports
Denver (4-0): A
The NFL’s top-ranked defense has carried the Broncos atop the AFC West. Reports of Peyton Manning’s demise also appear greatly exaggerated now that new head coach Gary Kubiak has adjusted his offense to take advantage of the quarterback’s strengths.
Chris Humphreys-USA TODAY Sports
Cincinnati (4-0): A
These don’t look like the same old Bengals who would often look great one week and mediocre the next. Consistency and one of the NFL’s most talented rosters have Andy Dalton and Cincinnati off to a 4-0 start for the first time in a decade.
USA TODAY Sports
Carolina (4-0): A
C-A-M for M-V-P? Carolina’s quarterback is in the mix as Newton carries an offense without a true No. 1 wide receiver. Josh Norman also has emerged as the NFL’s hottest cornerback following two games with interception returns for touchdowns.
USA TODAY Sports
Atlanta (4-0): A
The NFL’s most pleasant early-season surprise has made Dan Quinn the early frontrunner for NFL Coach of the Year. Offensive coordinator Kyle Shanahan also has worked wonders getting the running game and quarterback Matt Ryan back on track.
Dale Zanine-USA TODAY SportsDale Zanine
Green Bay (4-0): A+
Injuries to skill-position talent haven’t kept quarterback Aaron Rodgers from delivering another MVP-caliber season. The defense also exorcised the ghosts from previous failings against San Francisco and Seattle in two victories.

New England (3-0): A+
The early comparisons being made to the 2007 squad that went undefeated during the regular season might not be premature. Rob Gronkowski and the Patriots are sticking it to the rest of the NFL in the wake of the 'Deflategate' scandal.
