STACKED’s take

NeutralProjection

Loses Allgeier (7.2 PPG) to Arizona; trails Gibbs due to Falcons' weaker 21.2 PPG projection.

Comparable profile to Jamir Gibbs with 17 games played in all three NFL seasons and back-to-back 20+ PPG seasons; loses Tyler Allgeier (7.2 PPG, 8.4 carries/game) to Arizona, replaced by lesser back Brian Robinson. Similar opportunity gain to Gibbs but Atlanta's 21.2 PPG team projection trails Detroit's 26.1 PPG, making Gibbs the marginal edge at pick 1.
