How Does an Expansion Draft Work?
On this page5
An expansion draft is the special selection process that stocks a brand-new franchise. Existing teams protect a set number of players, and the expansion team then drafts from everyone left unprotected — usually one player per team. League rules balance giving the newcomer enough talent against letting established clubs keep their core.
The basic mechanism
Before the draft, each existing club submits a protected list of players it keeps safe. Everyone left off those lists forms the available pool. The new team selects from that pool to assemble its first roster. How many players a team can protect — and any position rules — is set by the league and decides how strong the newcomer can be.
Protection rules shape the outcome
| Protection is… | Result for the new team |
|---|---|
| Tight (few protected) | More quality available — stronger start |
| Loose (many protected) | Mostly fringe players — slower build |
Leagues have steadily loosened protection over the years, because uncompetitive expansion teams hurt the overall product.
Side deals: the hidden game
Much of the value comes off the board. Existing clubs cut side deals with the expansion team — a pick or prospect in exchange for taking, or avoiding, a specific player (often an unwanted contract). These agreements can be worth more than the drafted players themselves, and shrewd new franchises use them to accelerate the build.
The Vegas blueprint
The NHL’s 2017 draft for the Vegas Golden Knights is the model: favorable rules plus aggressive side deals produced an instantly competitive roster, and Vegas reached the Stanley Cup Final in year one. It changed how leagues design expansion terms.
Not the only tool
The expansion draft is the distinctive first step, but a new club also uses free agency, trades, and the entry draft (sometimes with bonus early picks) to build a lasting roster. It is the closed-league counterpart to how open pyramids handle new clubs through promotion and relegation — a contrast at the heart of debates like the European Super League.
Frequently asked questions
How does an expansion draft work?+
Before the draft, each existing team submits a protected list — a set number of players it keeps safe. Everyone left off those lists forms the available pool. The [expansion team](/what-is-an-expansion-team/) then selects players from that pool, typically one from each existing club, to build its initial roster. The league sets the protection limits and any restrictions, which shape how much talent the newcomer can grab.
How many players can a team protect in an expansion draft?+
It varies by league and by the specific expansion rules agreed for that year. A common structure lets a team protect a certain number of players (for example, around 7–11 depending on the sport and format), leaving the rest exposed. Some formats let teams choose between protecting more skaters or more of another position group. The tighter the protection, the stronger the expansion team can become.
Can teams make deals to influence an expansion draft?+
Yes, and it is a big part of the strategy. Existing clubs often negotiate side deals with the expansion team — offering a draft pick or prospect in exchange for the newcomer taking (or avoiding) a specific player, such as an unwanted contract. These side agreements can be as valuable to the expansion team as the players it drafts, which is how savvy new franchises accelerate their build.
Why did older expansion drafts produce weak teams?+
Early expansion drafts let existing teams protect most of their useful players, so newcomers were left with fringe talent and often took years to become competitive. Leagues have since loosened protection rules to give expansion teams a fairer shot, partly because uncompetitive new clubs hurt the league's product and TV appeal. The result is a much better on-ice or on-field start for modern entrants.
What was the most successful expansion draft?+
The NHL's 2017 expansion draft for the Vegas Golden Knights is the standout. Favorable protection rules, shrewd selections, and a flurry of side deals let Vegas assemble a genuinely competitive roster immediately — and the team reached the Stanley Cup Final in its very first season, a result that reshaped how leagues design expansion rules.
Is an expansion draft the only way a new team gets players?+
No. The expansion draft provides the core, but a new franchise also uses regular free agency, trades, and the normal entry draft — sometimes with extra early picks granted as part of the expansion terms. The expansion draft is the distinctive first step, but building a lasting roster relies on all the usual roster tools too. See our [expansion team](/what-is-an-expansion-team/) overview for the full picture.
Do soccer leagues use expansion drafts?+
Rarely, because most soccer runs on [promotion and relegation](/promotion-and-relegation-explained/) rather than closed franchises, so new clubs earn their place and sign players normally. Expansion drafts are a feature of closed franchise leagues — mainly in North America and some franchise-model competitions in other sports — where a new team needs a one-off mechanism to acquire an initial squad.
