All summer long, we try to show you how to play fantasy football the right way, whatever that means. Obviously it’s a nuanced and shifting discussion, and obviously it’s all contextual. What works best in my hometown league might not work best for your hometown league. There’s a lot of season to taste to this game.

But sometimes we need to take a step back and focus on how suboptimal thinking sneaks into our decision trees. That’s our mission for today, to patch some of the leaks that might be holding you back.

Here are four common mistakes that fantasy managers, even good ones, often make.

Not knowing the league rules and settings

I know this seems like a painfully obviously thing to list, but it’s a common error. I know, because I make it myself sometimes — and there’s no reason for it.

It’s no fun to read the rules or audit the settings, I get it. In some of the leagues I play in, the rulebook is long and unwieldy, a cumbersome read. And like so many fantasy managers, I’m in a ton of leagues (too many to count), so at times it becomes tempting to cut this corner. But if you’re not clear on the game you’re playing, errors are sure to follow.

So let’s just make sure we put in the work and plug this leak. And I’m not just talking about scoring rules, I’m talking about every setting tied to a league. A common mistake tied to this: often managers are unaware of when free agency starts or when the waiver process begins. Thirty seconds in your online calendar today can cover you for a missed opportunity later.

Buying insurance when it doesn’t make sense

Modern baseball theory holds that sacrifice bunts are rarely a good idea. The game is dominated by launch angles and home runs, to the point that giving up an out and advancing a runner from first to second is rarely the proper play. When you hand outs to the other team, you cap your scoring upside.

What does this have to do with fantasy football? Well, when you go out of your way to draft the NFL backups of your primary starters (especially at running back), you’re essentially bunting. You’re capping your upside. You’re playing for the small inning.

In the early part of the fantasy year, I want you to play for the big inning. I want you to try to build the most dynamic juggernaut possible. Sure, you can draft backup running backs, intriguing stash-and-hope runners, but do it when it’s not tied to one of your primary starters. Draft the backups that benefit if your opponents encounter bad luck. Build a roster that can improve — not merely survive — when chaos happens.

I don’t want you to draft like your early picks are going to flame out. I want you to draft like your early picks were the right picks. Stop playing it safe and hurting your ceiling.

Let’s be clear, the understudy back can make sense later in the year — much like bunting can make sense in a baseball game, later in the day. The winning scenario narrows the later we get in any contest, and with that in mind, you act accordingly. If you’re crushing the league come early November and you want Tony Pollard to back up your Ezekiel Elliott — because your roster doesn’t have bigger problems that need solving — I can sign off. You’re already put a crooked number on the board.

In August, that’s the wrong way to think. Your goals should be much loftier the day you start assembling your roster.

Anchoring to previously-held opinions

Fantasy sports are essentially a game of opinions, your best guess against my best guess. The best fantasy managers are going to have plenty of takes. You compete for a few years, take down a trophy or two, you get some confidence and even some ego.

But remember, the NFL is a snow-globe league, the American sport with the most year-over-year variance. It’s also the fantasy sport where context matters the most. A journeyman running back might become fantasy royalty if he lands in the right offense. And a walk-in Hall of Famer like Randy Moss can fall off the planet when he’s on a team like the 2006 Raiders.

I have plenty of strong player and strategy takes today, just like I did a month ago, three months ago, or six months ago. But everything’s written in pencil. When the facts shift, I’m willing to change my mind. And when nuances that I overlooked are brought to my attention, I’m willing to change my mind, too.

The goal is to figure out the new season before your opponents do. And with that in mind, you have to be willing to be selectively aggressive when opportunities arise. James Robinson was an undrafted nobody 12 months ago, but he quickly earned a Circle of Trust pass. Anyone who was unwilling to stay open minded in this case paid a price.

Being paralyzed by fear

Paradox of Choice is a fascinating concept, the idea that otherwise-smart people can be overwhelmed by alternatives. It’s not uncommon for a fantasy manager to tell me they prefer a roster of minimal depth over a roster of fantastic depth, because they aren’t forced to make difficult choices every week. (Obviously, a deep roster can often be traded into an even more-dynamic set of starters, but let’s ignore that for now.)

Some managers are afraid to bench a player because said player cost a lot at the draft, or in free agency.

Some managers are afraid to make a trade or a FA move because they’re obsessed with how bad they’ll feel if the decision turns out to be wrong. Friendliest Loss remains a pox in our decision-making world. Too many fantasy players will settle on the choice that will give them the least amount of pain if it turns out to be wrong — no matter if that choice reflects what they view the most likely winning scenario.

Don’t be afraid of making a mistake, amigas and amigos. Tricky decisions are like bluffs in poker — if you don’t have one blow up on you ever so often, you are playing far too conservatively. Fortune favors the brave. If you insist on keeping both of your feet on first base, you’ll never be able to steal second.

I’m not suggesting you do wacky or crazy things just for the sake of it. I still want you to make good decisions, sound decisions. But focus on the likelihood of your decision working, and what the payoff may be. Don’t get tripped up on what the regret will feel like if you’re wrong. That’s not how successful people think.
