The Fragility of the Group of Five: How Realignment is Threatening G5 Stability

The instability of the NCAA’s Group of Five (G5) conferences has reached a critical point as member churn accelerates toward the Power 4. According to current realignment trends and revenue disparities, conferences such as Conference USA and the American Athletic Conference (AAC) face existential risks as their most profitable programs migrate to higher-revenue leagues, leaving remaining members with diminished visibility and funding.

Why is member churn destabilizing Group of Five conferences?

Member churn is driven by a massive revenue gap between the “Power 4” (ACC, Big Ten, Big 12, and SEC) and the G5. The Big Ten and SEC have secured media rights deals worth billions of dollars, creating a financial incentive for any G5 program with a strong brand to jump ship. According to ESPN, the pursuit of these payouts forces G5 conferences into a cycle of desperation, where they recruit lower-tier programs to fill gaps left by departing members.

This cycle erodes the “strength of schedule” for the remaining teams. When a conference loses its anchor programs, its overall prestige drops, making it harder to attract recruits and secure favorable bowl game tie-ins. This creates a “domino effect” where the departure of one marquee team triggers a mass exodus of others seeking stability elsewhere.

Which G5 conferences are most at risk?

Conference USA (CUSA) and the American Athletic Conference (AAC) have experienced the most significant volatility. Conference USA has undergone a near-total transformation of its membership over the last several years, losing core teams to the AAC and other leagues. This churn has left CUSA struggling to maintain a cohesive regional identity, which is critical for reducing travel costs and maintaining local fan interest.

The AAC has similarly struggled after losing several high-profile members to the Big 12. While the AAC remains a powerhouse relative to other G5 leagues, the constant loss of “Power-level” programs to the Big 12 prevents the conference from establishing long-term stability. According to reports from The Athletic, the AAC’s ability to remain a “bridge” conference depends entirely on whether the Power 4 stop poaching its top members.

How does the collapse of the Pac-12 affect the G5?

The dissolution of the original Pac-12 structure acted as a catalyst for further G5 instability. When the Pac-12 collapsed, it created a vacuum that the Big 12 and Big Ten filled by absorbing former Pac-12 schools. This shifted the geography of college football, leaving several G5 programs in the West—particularly in the Mountain West—vulnerable to being absorbed or left behind.

The “trickle-down” effect is clear: as the Power 4 expand, they don’t just take the best teams; they rewrite the rules of membership. This forces G5 conferences to compete for a shrinking pool of viable members. If a Power 4 conference decides to expand again, the most stable G5 conferences, like the Mountain West, could see their membership gutted overnight.

What happens to a conference that becomes defunct?

A conference becomes defunct when it can no longer maintain the minimum number of members required by the NCAA to operate as a sanctioned entity. If a G5 conference collapses, the remaining schools face three primary options:

• Absorption: Other G5 conferences absorb the remaining members to maintain their own viability.
• Independence: Schools go independent, though this is financially ruinous for most non-Power programs due to the loss of guaranteed conference scheduling and revenue sharing.
• Rebranding: The conference attempts to rebuild from scratch with a completely new set of members, often sacrificing its historical identity.

The legal fallout involves the termination of media contracts and the redistribution of exit fees. According to NCAA guidelines, conferences must adhere to specific bylaws regarding membership, and a total collapse would trigger a complex redistribution of assets and liabilities.

Power 4 vs. Group of Five: Revenue Contrast

The primary driver of this instability is the financial divide. While exact figures vary by school, the disparity is stark:

This gap ensures that any G5 program with the opportunity to move up will do so, regardless of the impact on their current conference partners. This creates a permanent state of instability for the G5, where the “success” of a program—growing its brand and winning games—actually makes it more likely to leave its conference.

As the NCAA moves toward a potential “super league” model, the G5 conferences may eventually cease to exist in their current form, replaced by a tiered system that formally acknowledges the financial divide between the elite and the rest of collegiate athletics.
