Kyle Shanahan’s play-calling prowess was on full display last season as he orchestrated one of the NFL’s most prolific offenses as the Falcons’ coordinator.

Atlanta’s regular season ranked among some of the best offenses of all time, as the team’s site points out:

With a 38-32 win over New Orleans, Atlanta finished 2016 with 540 points – tied with the 2000 Rams for the seventh-most an NFL club has ever scored in a single season. That output is 71 points more than any other team accumulated this year and 176 points above the league average. Week 17’s triumph also marked the 11th time Atlanta had 30-plus points, the third-most ever in an NFL season, and its five 40-plus-point efforts rank second all-time.

Shanahan was able to generate top-five rankings in both passing and rushing behind league MVP quarterback Matt Ryan, star wideout Julio Jones and the running back tandem Devonta Freeman and Tevin Coleman.

While his 2016 regular season with the Falcons was far-and-away his best, Shanahan has produced top-10 offenses in six of his nine seasons as an offensive coordinator. His success at the helm earned him the top spot in Bleacher Report analyst Dour Farrar’s rankings of the best offensive scheme’s in the NFL:

Kyle Shanahan’s Atlanta Falcons offense was the NFL’s most effective through just about the entire 2016 NFL season (minus two quarters or so of Super Bowl action, of course), and there are multiple aspects of that offense Shanahan will take to the Bay Area as he gets ready for his first head coach position with the 49ers.

Shanahan’s inheriting a team that will offer the rookie head coach far less talent than what he had in Atlanta. Shanahan and new GM John Lynch received matching six-year contracts and took their first steps in a long rebuilding process this offseason. Shanahan will have his work cut out for him on offense, inheriting one of the league’s worst, which included the NFL’s last-ranked passing attack.

In response, the 49ers’ quarterback room has been completely overhauled. Colin Kaepernick and Blaine Gabbert have been replaced by veteran Brian Hoyer, backup Matt Barkley and 2017 third-round pick C.J. Beathard. Hoyer was one of the team’s first acquisitions at the start of free agency, having experience under Shanahan in Cleveland.

Farrar detailed the style of play Shanahan wants under center:

Shanahan prefers a mobile quarterback, or at least a quarterback who can run play-action and then roll out. It took a while for Matt Ryan to align with Shanahan’s “boot-action” concepts, but when he did, there was an entirely new dimension to his game. Shanahan prefers inside and outside zone blocking, though his blockers will run man-on-man gap schemes at times, and he will send receivers to all levels of the field.

The receiving corps has also been given a dramatic face-lift. The only prominent wide-out retained from 2016 was Jeremy Kerley – who re-signed with San Francisco on three-year deal after leading the team in receiving last season.

Torrey Smith was among the team’s prominent players released after getting of a five-year, $40 million contract in 2015 from former GM Trent Baalke. Lynch signed veteran Pierre Garçon, who had a career-year in Washington under Shanahan in 2013 with 113 receptions for 1,346 yards and five touchdowns.

Another marquee signing this offseason was former Ravens fullback Kyle Juszczyk. The four-year, $21-million dollar deal made Juszczyk the league’s highest paid fullback by a wide margin. Shanahan is one of the few coaches that utilizes a fullback, as Farrar highlights below, and the contract is likely an indicator of just how important Juszczyk will be the 49ers’ offense.

Running backs Devonta Freeman and Tevin Coleman might start in the backfield together and each move into the receiver group—perhaps one in the slot and one outside. A Shanahan staple was to take fullback Patrick DiMarco and move him from the backfield to the outside receiver formation—something fullbacks don’t generally do. But DiMarco caught seven passes for 52 yards in the regular season and three more for 43 yards in the playoffs, and he never carried the ball. He was a blocker and receiver, and that was that.

Shanahan’s pre-snap blurring of run and pass concepts is a crucial element to his offense. Not only does it force defenders to adapt, and often tip their hand in regards to their call, but it plays a key role in setting up his rushing attack.

With all this motion going on, and since Shanahan refused to let his offense ever be defined as static, running lanes would open for Freeman and Coleman precisely because defenses were set on their heels by the changes in pre-snap formation and the subsequent expansion of the passing game.

While the 49ers may not have the quarterback and receivers Shanahan enjoyed with Atlanta, San Francisco could put together a quality ground game in 2017.

Carlos Hyde is coming off his best season as pro and the 49ers have added a host of reinforcements at running back. Lynch and Shanahan signed veteran Tim Hightower, traded for Broncos’ Kapri Bibbs and took Utah’s Joe Williams in the fourth round of the NFL draft.

The pressure may be mounting for Hyde to prove he belongs in Shanahan’s scheme. He should benefit from the dynamic system his new head coach will bring to the 49ers’ offense.
