The Million Dollar Question

The Golden Rules

Rule #1: Start Your Studs - If you drafted someone in the first 3 rounds, they play unless they're injured or on bye. Don't overthink it.

Rule #2: Check the Injury Report - A player listed as "Questionable" who practiced all week is usually safe. "Doubtful" means find a backup.

Rule #3: Matchups Matter (But Not Always) - A great RB facing a tough defense is still better than a mediocre RB facing a weak one.

Rule #4: Volume is King - Players who touch the ball more score more points. Simple math.

Your Weekly Decision Process

Follow this exact process every week and you'll make better decisions:

Step 1: Lock in your obvious starters (your best players who are healthy)

Step 2: Check injury reports (Wednesday-Friday practice reports)

Step 3: Analyze tough decisions (for your flex spots and bench debates)

Step 4: Make final adjustments (Sunday morning, after checking inactive lists)

Most weeks, you only have 2-3 genuinely difficult decisions. Focus your energy there.

How to Analyze Matchups

When deciding between two similar players, ask these questions:

Who gets more touches? - The guy who gets 20 carries beats the guy who gets 12, even if the matchup is worse.

Is anyone injured? - Injuries to teammates can mean MORE opportunities for your player.

What's the game script? - Teams losing by 20 points throw more. Teams winning run more clock.

Home or away? - Home players typically perform slightly better, but it's the least important factor.

Pro tip: Don't overthink defensive matchups. A "tough" matchup might give up 15 points instead of 20. Your stud will be fine.

Common Start/Sit Mistakes

Mistake #1: Chasing last week's points - Just because someone scored 30 points last week doesn't mean they'll do it again.

Mistake #2: Sitting studs for matchups - Your first-round pick earned that spot. Trust them.

Mistake #3: Starting Thursday players by default - Don't lock in a mediocre Thursday player when you have a better Sunday option.

Mistake #4: Ignoring weather - Heavy rain and wind kill passing games. Check the forecast.

Mistake #5: Making Sunday morning panic swaps - If you spent all week on a decision, trust your Wednesday analysis.

The Flex Position Strategy

Your flex spot is where most start/sit decisions happen. Here's how to handle it:

In PPR leagues: Lean toward pass-catching RBs and consistent WRs

In Standard leagues: Favor players with touchdown upside

When in doubt: Start the player with the higher floor (more consistent points)

When you need a miracle: Start the player with the higher ceiling (boom potential)

Thursday tip: NEVER play a mediocre player in your flex on Thursday. Always keep flex for Sunday players so you have maximum flexibility.
