In January, after Falcons running back Tevin Coleman caught a 14-yard touchdown pass in a divisional-playoff win over the Seahawks, Brian Hoyer grabbed his phone and sent a message to Atlanta offensive coordinator Kyle Shanahan. In 2014, Terrance West led Browns running backs with 11 catches (64 yards) and Cleveland’s running backs and fullbacks accounted for 12 percent (32 of 274) of the team’s receptions. In 2016, Devonta Freeman led Falcons running backs with 54 catches (462 yards) and Atlanta’s running backs and fullbacks accounted for 25 percent (93 of 374) of the team’s receptions. A 49ers running back hasn’t had more than 30 receptions in a season since Frank Gore had 46 in 2010. [...] I think an offense that’s going to do well is always evolving to what is going on in the league. Hoyer mentioned fullback Kyle Juszczyk, who has 78 catches the past two seasons, as a likely frequent target in the passing game. Running back Carlos Hyde had a career-high 27 catches last year and Tim Hightower ranked second among running backs in receptions (63) in 2009. Hyde said he spent plenty of time learning his passing-game assignments in the offseason. In this offense, running backs are more involved in the passing game.
