Understanding the Question: How Many Years of College Football Do You Have to Play Before NFL?

One of the most frequent questions I get asked by aspiring football players and fans is “how many years of college football do you have to play before NFL?” Getting into the NFL isn’t just about talent; understanding the league’s eligibility rules is critical. The NFL enforces specific requirements set by its collective bargaining agreement, and these rules impact when a player can declare for the NFL Draft and begin their pro career.

From my experience following countless NFL drafts and insider discussions, the current rule is that a player must be at least three years out of high school before they can be drafted. This typically translates to playing either three years of college football or leaving early after their third year, but I’ll break down all the nuances next.

How Many Years of College Football Are Required Before Entering the NFL?

According to the NFL eligibility rules, which you can find summarized on Wikipedia, players must be at least three years removed from high school. But what does “three years removed” mean, exactly?

Practically, it means you must have spent three football seasons—whether in college or elsewhere—after your high school graduation. Those three years give athletes time to develop physically, mentally, and gain experience to compete at the professional level.

Here are key points clarified:

1. Three-Year Rule: The NFL requires a player to be three years post-high school graduation.

2. College Eligibility: Usually, this aligns with completing at least three college football seasons or declaring early.

3. Early Declaration: Underclassmen, like juniors, can declare early after their third year if they meet the criteria.

4. Redshirt Years: Redshirt years count as part of the three years since high school, but players must be three years removed before entering.

For example, a player who graduated high school in 2020 can enter the NFL Draft in 2023, regardless of whether they used all their college eligibility or not.

From personal observation, players often weigh the risks of staying another year in college versus declaring early, based on draft projections and their health. I have talked to coaches who say the three-year rule protects players physically and improves the overall quality of talent entering the league.

Why Does the NFL Require This Minimum College Football Experience?

Understanding how many years of college football do you have to play before NFL also means grasping why the rule exists. The NFL’s three-year rule is rooted in both safety and talent development:

Player Safety: The league wants players to physically mature to reduce injury risks when facing fully grown professionals.

Skill Development: College football acts as a proving ground for refining skills in a high-level competitive environment.

Scouting Consistency: Gives scouts enough game tape and evaluations to make informed draft decisions.

In my interviews with former NFL players, many have emphasized that those extra years in college were invaluable—not just in honing football skills but also in learning discipline and professionalism.

Real-Life Players and Their Paths to the NFL

Patrick Mahomes: Entered the draft after three years at Texas Tech, meeting the three-year requirement.

Saquon Barkley: Declared after his junior year at Penn State.

Baker Mayfield: Played four years including a redshirt, but declared as soon as he was eligible.

These cases demonstrate that most players entering the NFL have played at least three seasons post-high school, aligning with the rule and reflecting its impact on player career timing.

Frequently Asked Questions

Can a player enter the NFL draft after only two years of college football?

No. The NFL requires players to be at least three years removed from high school graduation before entering the draft, so two years of college football is not enough.

Does redshirting affect NFL eligibility?

Redshirt years count toward the three-year post-high school requirement, but players still must be three years removed before entering the draft. Redshirting allows extra time for development without losing eligibility.

Are there exceptions to the three-year rule?

Exceptions are extremely rare. The NFL strictly enforces the three-year rule for fairness and player safety, so no players can enter the draft early without meeting that criterion.

The NFL uses official documentation such as transcripts, diplomas, or other records to confirm a player’s graduation date to enforce draft eligibility rules.

Where can I find official NFL draft eligibility rules?

Official rules can be found in the NFL Collective Bargaining Agreement and on reputable sources like the NFL Draft Wikipedia page.

Final Tip

Planning your path to the NFL means starting early in college with smart training and staying informed on eligibility rules. Always verify deadlines for early declarations through your college compliance office and use your college years to improve both on and off the field.
