Brennan Marion instantly became the center of Colorado football conversations after Deion Sanders hired him as the new offensive coordinator, a move made just days after Marshall Faulk resigned from CU as the running backs coach.
Marion arrives with a national reputation as the mastermind behind the Go-Go Offense, a scheme built on speed, layered misdirection, and explosive play design.
His system is known for stressing defenses from the first snap, creating easier reads and bigger opportunities for quarterbacks. With Marion stepping into Boulder, Colorado’s offensive identity shifts overnight, giving the program a play-caller built for modern, high-powered production.
All about Brennan Marion’s Go-Go offense
Brennan Marion’s Go-Go offense is built on creating simple problems that turn into big advantages. Instead of overcomplicating everything with endless formations, he uses alignment to control what the defense does before the ball is even snapped.
Brennan Marion explained the idea clearly when he said, “I wanted to get everybody to play a four four, cover, three, you know, base defense. I was trying to get everybody just to play cover 3 base defense,” and that alone tells you how intentional the system is.
Once a defense locks into that predictable look, the rest of the plan unfolds. Brennan Marion added, “So we could throw the ball exactly where… the spots are gonna be open out on the field and be able to take your shots, and take advantage of the defense so when they overload the side then we run the ball weak.”
He added, “When they overload the backside, then we run the ball strong. You know, just the kind of dictate where the ball’s already gonna go before the play starts.”
Brennan’s attention to detail is what makes the scheme dangerous. He even shared a tabled game plan mapping out where every player should be lined up to make sure the Go-Go offense consistently tilts the field in their favor.
How Brennan Marion’s Go-Go Offense Can Finally Fix Colorado’s Struggling Run Game
Brennan Marion gives Colorado something it hasn’t had in years: a run game with structure and purpose. His Go-Go offense creates angles that help a struggling line win blocks without needing overpowering talent.
By forcing defenses to guess, Brennan Marion opens lanes that didn’t exist in CU’s traditional looks. The constant threat of motion, misdirection, and dual-back action keeps linebackers frozen, which is exactly what a historically poor rushing team needs.
With Brennan Marion calling plays, Colorado can finally build a balanced attack where downhill runs, weak-side cuts, and explosive play-action all work together instead of fighting against each other.
