ESPN has an article ranking the worst loss ever for every NFL team:
Their Lions entry:
Dec. 3, 2015, regular season
Ford Field, Detroit
The Lions’ history includes no shortage of heartbreaking and bizarre moments. You can take your pick with these situations, which includes becoming the first team in NFL history to lose twice in a season on 50-yard field goals on the final play of regulation, per Elias Sports Bureau research, just this season. But one crushing defeat sticks out: the Dec. 3, 2015, loss to the Packers, when quarterback Aaron Rodgers connected with Richard Rodgers for a 61-yard Hail Mary as time expired. It was the longest game-winning, game-ending Hail Mary in NFL history, per Elias, and lifted the Packers to a stunning 27-23 victory. – Eric Woodyard
Certainly worthy of consideration, but I think there’s some recency bias creeping in here (a common problem with ESPN).
Because this was just a regular-season game.
My vote would be for this:
1983 playoffs. Lions at 49ers.
Lions were about to beat a San Francisco team that had already won a Super Bowl – this was after “The Catch” between Dwight Clark and Joe Montana. I’ll say it again. The Lions were about to beat Joe Montana’s, Bill Walsh’s 49ers in the playoffs, in their home stadium. They had the lead in the 4th quarter, 23-17, riding Billy Sims. But Montana drove the 49ers down on a 70-yard drive, completing passes all over the field as he so often did, for a Freddie Solomon TD pass with 1:30 left to give San Francisco a 24-23 lead.
BUT WAIT! The Lions mount a last-minute drive of their own!
All they needed was ever-reliable kicker Eddie Murray to make a 42-yard field goal. Above we see Lions Coach Monte Clark raising a prayer skyward.
We knows how this goes for Detroit. Murray choked. The kick wasn’t even close. 49ers win.
I think the entire trajectory of the Lions franchise changes if that field goal is good.
A postscript to that game: Murray is (probably rightfully) given the blame for missing that kick. And an NFL kicker as good as he is has GOT to make a 42-yarder in a clutch situation like that.
But check out Lions QB Gary Danielson’s stat line from that game:
24 of 38, 236 yards, 0 TDs, 5 INTs.
How in the world were the Lions still in that game? Two words: Billy Sims. 114 yards and 2 TDs.
But how Danielson has escaped fan ire for that outcome … he should be sending Murray a Christmas gift every year.

Another one worth mentioning – it’s before my time, but it has to be ranked higher than a regular-season loss, no matter how heart-wrenching that loss may have been: The Greg Landry-led Lions losing to the Craig Morton-led Cowboys 5-0 in the 1970 playoffs.
Many oldtimers will tell you that Lions team was good enough to win a championship.
