What is the probability that joey aguilar is successful in getting another year of eligibility?
It isn’t possible to put an exact mathematical probability on whether Joey Aguilar will be granted another year of eligibility — but based on the information currently available, there are clear factors both for and against his chances, and experts and sources seem to be uncertain or mixed about the outcome:

Factors that suggest he has a decent chance
1. The court granted a temporary restraining order:
A Tennessee judge already ruled Aguilar “has demonstrated a substantial likelihood of success on the merits” in his eligibility claim — which is exactly the legal standard needed for a preliminary injunction if the judge later applies it in full.
2. He remains protected from enforcement of the rule for now:
The temporary restraining order has been extended, meaning he can practice with the team while the judge considers the full injunction, demonstrating real legal momentum.
3. Similar legal challenges have succeeded recently:
Other players (like in the Pavia case) have obtained injunctions against NCAA eligibility rules that count junior college years — and Aguilar’s arguments are part of the same broader legal trend challenging those longstanding rules.

Factors that suggest his chances aren’t a sure thing
1. No final ruling yet:
As of the latest reports, the judge has not yet decided whether to grant a full injunction that would allow Aguilar to play in 2026; the decision has simply been delayed.
2. Conflicting views online and among fans:
Some observers believe an extra year for Aguilar is unlikely absent a strong waiver or clear legal precedent that carries the day.
3. The NCAA is actively defending its rules:
The NCAA is contesting these eligibility challenges on legal and regulatory grounds, and that defense — combined with judges’ hesitancy to broadly rewrite eligibility rules — means not all courts will rule in Aguilar’s favor.

What the current snapshot suggests
Legal experts and court precedent say: He has a solid argument and has already cleared one early legal hurdle (the restraining order) — a positive sign.
But: A preliminary injunction isn’t guaranteed just because the restraining order was granted. The judge still has to decide if the full injunction — which directly impacts his eligibility — is appropriate.
So rather than a single probability number, the best way to think about it is:

Reasonably plausible or moderate chance: He’s not an underdog, and his legal position has some strong elements.

Not guaranteed: There’s still substantial uncertainty because the judge has not yet committed to the full injunction.

In plain terms
At this stage, many observers would describe his chances as “moderate to favorable, but far from certain.” The fact that he already convinced a judge he’s likely to succeed on the merits is significant — but until the injunction is actually granted, we can’t say he’s likely or certain to get another year of eligibility.
If you’re looking for a rough qualitative sense of likelihood based on current legal signals:

Better than 50/50 but probably not overwhelming (e.g., not > 70–80% certain) — in legal disputes like this outcome is uncertain until the judge’s ruling.
