If you are a League Manager (LM), you can change settings by going to your league or team page, clicking on "League," then "Settings." Here you will find general settings, which you can change by clicking "Edit." For full details on how to create an ESPN league, click here.
Number of Teams: Ideally, you want an even number of teams in your league, because you compete head-to-head each week. However, if you choose to use an odd number, your schedule will include bye weeks (and teams will miss out on the fun during those byes).
If you go with eight teams or fewer, your rosters will be stacked with plenty of star power, though you can counter that by enlarging the size of each team's roster, like using two starting quarterbacks or extra running backs, wide receivers, tight ends or flex/OP (offensive player) spots. This can be a fun way to get the ball rolling if you are a newbie.
Ten teams is the traditional size of most leagues. The player pool is deep enough that each team has stars, but managers will still have the challenge of picking up free agents and players who are getting hot.
Make League Viewable to Public: If you want to be able to let people who aren't in your league (friends, family, etc.) see your league pages, make it "Public" and share your league link with them.
In an age when there are so many quality quarterbacks, starting two quarterbacks in leagues with 10 or fewer teams gives you an extra challenge, because you'll have to dig all the way through the top 20-plus quarterbacks each week. Using a pair of starting QBs is a little problematic in leagues of 12 or more, because there is a max of 32 starting NFL quarterbacks each week -- and even fewer during bye weeks. One way to remedy that is to use an Offensive Player Utility (OP) spot instead of a second QB. The OP can be a quarterback, running back, wide receiver or tight end.
Your league doesn't have to limit itself to offensive players, either. You can use Individual Defensive Players (IDP) by selecting defensive positions, like Cornerback (CB), Linebacker (LB), Defensive Tackle (DT) or Defensive Player Utility (DP -- any defensive player position). This allows you to use players on both sides of the ball and really test -- and even increase -- your all-around football knowledge.
Scoring Type: Head-to-Head Points. This means each week each team in your league plays one opponent. The players on each team
roster earn points for their production on the field. The team with more points in its weekly head-to-head battle earns a win; the team scoring fewer points gets a loss.
Custom: You can set your scoring however you may choose or you can use (or at least begin with) any of the following preset scoring options.
If you want to get more adventurous with your scoring settings, you can tighten them up by making higher yardage thresholds (say, one point per 15 rushing yards, instead of 10) or giving 0.5 points per reception (instead of 1.0). Or you can go the other direction, and look to boost your scoring ability even more by granting bonuses for 100-yard rushing/receiving performances or 300-yard passing games.
To invite managers to your league, click on the "Invite Managers" button on the league home page or click on "League" and then "Members." There, you'll be able to add their names and email them an invitation.
If your league consists of 12 or more teams, you may want to consider going to three divisions with the three division winners earning the top seeds in the playoffs, and the one or three teams with the next-best records earning the other playoff berths.
You can also create leagues that don't use separate divisions. To do so, go to the "Teams and Divisions" option on the League Settings page, choose the same division for each team in the dropdown menu, then click the option to "Delete Division" for the division you cleared out. Then click "Save Changes" and you're all set. The benefit of not using divisions is that the top overall records will earn playoff spots and seeds. Often in leagues that use divisions, a potential wild-card team misses the playoffs because a team with a worse record won the other division.
Observe ESPN's Undroppable Players List: This is basically a safety net to ensure that managers in your league won't drop a star player who could affect the outcome of your league via collusion or tanking. Any player on our undroppable list can't be released to waivers. Note that we may take players off the list if they are injured or no longer warrant being on the list because of poor performance. If you genuinely trust all of your fellow managers to not mess with the integrity of the league, say, "No" to this setting. Generally speaking, though, it's wise to just be safe and let ESPN declare players who should not be droppable.
Lineup Changes: You can choose to lock lineups when the first game of the week starts, typically Thursday evening. This is a good setting if your managers don't have a lot of time to spend obsessing about their teams throughout the week, because roster moves can be made only Tuesday, Wednesday and Thursday (prior to kickoff). The downside is that since you have to set your official lineups by Thursday evening most weeks, you can't wait for injury information you may get Saturday or Sunday morning to make lineup and waiver moves. Most leagues use the setting that allows you to change your lineup right up to the start of each individual player's kickoff that week. This allows you to find out if a player is active/inactive due to injury, react to the score of your game against your opponent (e.g., using a safer play if you are in the lead or a riskier upside option if you're behind), etc. It also helps avoid situations where a player gets hurt in warmups or gets benched unexpectedly.
Trade Deadline: Most leagues allow unlimited trades so managers can improve their rosters throughout the season. However, including a Trade Deadline is generally a good idea, because you don't want managers who have no chance of making the playoffs in the waning weeks of your regular season making trades with managers who are deep in a playoff chase. You can see how that could mess with the integrity of the league. On the other hand, many keeper leagues don't include a deadline, because a team that is out of the race for this season could still make trades to improve their teams for the next season -- even if that gives a significant boost to an opponent this season -- without affecting the league's overall integrity.
