Green Bay's Week 1 roster is the NFL's youngest and least experienced, by a wide margin. At 25.28 years average, the Packers sit comfortably under the league average while boasting 3.41 years of experience and a 6.24-foot, 247-pound profile that favors speed and athleticism over bulk. Nine rookies bolster the youth wave, with only two players over 30, suggesting volatility but big upside as development plays out. Fantasy take: monitor early snaps and growth trajectories across WRs and defenders as the roster finds its rhythm.
