Ever since Dan Campbell took to the podium for his introductory press conference in Detroit and made eyebrow-raising statements about biting the kneecaps of opponents, the Lions have had a strong following as the 'second favourite team' of many in the NFL world.
Their reputation in that regard has been furthered by Campbell's aggressive decision-making and the impressive way in which he and his staff have developed their young talent.
But eventually, rebuilds – like the one the Lions started when they traded franchise quarterback Matthew Stafford to the Los Angeles Rams for a host of draft picks – must yield results.
When the Lions dropped to 1-6 with a home defeat to the Miami Dolphins in Week 8, it was fair to question if Campbell was the right man to lead a rebuild.
Since then, the Lions have won five of their last six games and, in a top-heavy NFC, are now in with a shout of sneaking into the playoffs as a Wild Card.
With only one of their final four opponents owning a winning record, the Lions look well-placed to complete an unlikely run to the postseason. However, if they get there, will Detroit be a threat?
Looking solely at the offense, there is plenty of reason to suggest the Lions can challenge to spring a first-round upset.
The Lions rank seventh in the NFL by yards per play (5.86) and possess an exciting combination of a well-rounded running back room and an explosive downfield passing game.
Detroit's offense has produced 46 pass plays of 20 or more yards, the fourth-most in the NFL, while the running back combo of D'Andre Swift and Jamaal Williams has delivered both efficiency and potency. Swift's average of 5.36 yards per carry is the fifth-best among backs with at least 50 carries and Williams leads the league with 14 rushing touchdowns.
The mix of an effective ground game and an aerial attack featuring a legitimate number one receiver in Amon-Ra St. Brown, whose presence is supplemented by that of D.J. Chark and the return of rookie speedster Jameson Williams from a knee injury suffered in his final college game has turned the Lions' offense into an extremely difficult one to stop, with quarterback Jared Goff - acquired as part of the Stafford trade - facilitating their outstanding production with a remarkable renaissance.
Cast off by the Rams when viewed as a quarterback Los Angeles won in spite of, Goff has been one of the best signal-callers in the NFL when defenses know he is passing.
Indeed, as of Week 14, Goff was averaging 0.96 yards over expected in expected passing situations, putting him sixth among quarterbacks with at least 100 such plays.
The Lions can run the ball well and they can produce through the air when everyone knows what is coming, but there are clear weaknesses that figure to be exploited in the postseason.
Detroit's offensive line, was 23rd in pass block win rate heading into Week 15. In a postseason where they could face the fearsome defensive lines of the San Francisco 49ers, Dallas Cowboys and Philadelphia Eagles, an inability to protect Goff would obviously be a huge detriment to the Lions.
And the Lions' defense would also be a massive concern heading into a potential postseason campaign. The Lions rank last in the NFL in yards per play allowed, giving up an average of 6.22.
But that defense has stiffened in recent weeks and has shown a habit for making game tilting plays. Since firing their defensive backs coach Aubrey Pleasant on October 31, the Lions are second in takeaways (11) and tied-fourth in points off takeaways (28), with rookie second overall pick Aidan Hutchinson, who has seven sacks on the season, enjoying an increasing influence in stopping the drives of opposing offenses as he did in last week's victory over the 10-win Minnesota Vikings.
The defeat of Minnesota represents the signature win of a team few had anticipated would be in position to play in the second week of January. The Lions were also unfortunate not to beat the Buffalo Bills on Thanksgiving, but that narrow 28-25 loss arguably represented a more accurate representation of where they are in their evolution.
The Lions can trouble the league's elite, but they still have too many holes to be considered a threat to do damage in the postseason. Still, in year two of the Campbell era, that is a place Detroit should be more than happy to be.
