Video: Your Leaguemates Are Completely Ignoring These Coaching Changes
Kirk Cousins has not gone under center very much uh over the past couple of seasons since he tore his Achilles... Kubak is like damn I just have I am like so limited by Cousins having to be in the shotgun or not being able to actually run an under center offense

STACKED’s take

Post-Achilles limitations restrict Cousins to shotgun, constraining Kubiak's scheme.

Cousins has not gone under center much since tearing his Achilles, severely limiting his ability to run Kubiak's efficient play-action offense which requires quarterback mobility and the ability to turn his back to the defense. Kubiak is constrained by having to keep Cousins in shotgun, unable to actually run an under-center offense, which may force the team to turn to Fernando Mendoza sooner than expected if Cousins proves too restrictive for the offensive scheme.
