Did The Packers Squander Aaron Rodgers?

The dismissal of Green Bay coach Mike McCarthy — who was let go after the Packers’ stunning home loss to the Arizona Cardinals on Sunday — wasn’t exactly a shock. Perennially tabbed as a Super Bowl contender out of the NFC, McCarthy’s team had gone just 11-16-1 over the past two seasons, including a disappointing 8-9-1 in games that featured future Hall of Fame quarterback Aaron Rodgers as Green Bay’s primary passer.1 It was time for a change along the sidelines that Vince Lombardi once roamed.

Things weren’t always so bleak on the frozen tundra. The McCarthy era had its high points, particularly early on — when he and Rodgers appeared to have Green Bay positioned on the cusp of a potential dynasty. But between postseason near-misses, roster changes, injuries and coaching miscues, McCarthy’s Packers never fulfilled that promise. Instead, it’s fair to wonder whether Green Bay squandered the prime of one of the most talented QBs in NFL history.

The Packers team that McCarthy inherited in 2006 from Mike ShermanThough their defense was shredded by Matt Ryan and the Falcons for 493 yards, ending the streak.

‘>4 By then Rodgers was 34 years old, so a sense of urgency was setting in when 2017 came and went without a playoff berth — even though that could be written off as the byproduct of Rodgers missing nine starts.

The 2018 season was always going to be the real crossroads for McCarthy. With a healthy Rodgers leading the way, the Pack could always count on contending in the past, so this year’s expectations were no different. But Rodgers’s numbers have been merely good, not great. Brett Hundley isn’t around anymore to take any blame. And unlike in 2015, when Green Bay was talented enough to survive despite a downturn in its QB’s individual stats, there has been no answer from the team’s supporting cast this time around. It all came crashing down around McCarthy in the loss to Arizona as 13½-point favorites, Green Bay’s single most disappointing defeat since the merger according to Pro-Football-Reference’s point-spread data.

We can visualize the Packers’ decline over McCarthy’s final few years at the helm using FiveThirtyEight’s Elo ratings. Specifically, I’ve been tinkering with an experimental version of Elo that keeps a separate adjustment for the primary QB in each game, similar to how we treat starting pitchers in our MLB ratings.In addition to the lack of starters from recent drafts, only two of the team’s current starters were drafted by a team other than Green Bay. Again, this was the byproduct of the Packers’ religious devotion to drafting and developing their own prospects, but that plan only really works when you draft well.

‘>6 Combine those infrastructural problems with criticisms of McCarthy’s offensive scheme (criticisms of a perceived lack of innovation that Rodgers apparently shared), plus legitimate complaints about Rodgers’s own decline in performance, and a season like this was bound to happen to Green Bay sooner or later.

Even so, it came contrary to preseason predictions. Going into the schedule, you might have penciled in this week’s matchup against the Atlanta Falcons as a marquee game with playoff implications. Instead, it will be the third-worst game of the week, according to our combination of matchup quality (i.e., the harmonic mean of the teams’ Elo ratings in each game) and game importance (how likely it is to swing every team’s odds of making the playoffs):7

Although the Packers hadn’t replaced a coach at midseason since 1953, Sunday’s loss forced their hand. Now they’ll need to figure out who’s next, from a candidate list that includes big names among both pro coordinators (Josh McDaniels) and up-and-coming college coaches (Lincoln Riley). They’ll also need to hope Rodgers’s issues were more related to McCarthy’s offense and less to his getting older and less productive — basically, that the next Packer coach will be more Mike Shanahan to Rodgers’s John Elway than Jimmy Johnson to his Dan Marino. So while the Packers may not have much on the line over the rest of their games, this promises to be the most interesting offseason Green Bay has had since Favre was retiring and unretiring more than a decade ago.

FiveThirtyEight vs. the readers

Make sure to check out FiveThirtyEight’s Elo ratings using our NFL prediction interactive, which simulates the rest of the season 100,000 times and tracks how often each team should make the playoffs and win the Super Bowl. And did you know you can also pick against the Elo algorithm in our prediction game? Maybe you can also climb up our giant leaderboard (or, if you’re like me, fall down it with each passing week).

Here are the games in which Elo made its best — and worst — predictions against the reader picks last week:

Home teams are in bold.

The scoring system is nonlinear, so readers’ average points don’t necessarily match the number of points that would be given to the average reader prediction.

After a series of narrow wins at midseason, the algorithm handed the readers their worst loss (-55.2 points on average) since Week 3. Some of the blame can go to the subject of this column — the Green Bay Packers, whose loss not only cost Mike McCarthy his job but also cost users 10.5 points on average. But readers were also burned by the Jaguars’ win over the Colts and the Cowboys’ upset victory over the Saints. Add it up, and Elo has beaten the average reader 12 times in 13 weeks this season.

But congrats to Mike Edelstein, who led all users in Week 13 with 137.0 points, and to one of my favorite leaderboard names, Greg Chili Van Hollebeke, who maintained his No. 1 ranking on the season with 1,002.1 points. Thanks to everyone who has been playing — and if you haven’t, be sure to get in on the action! You can make picks now and still try your luck against Elo, even if you haven’t played yet.
