Who Should I Start Tool

Week 3 Player Decisions. Today's focus is on specific defenses: Kansas City Chiefs, Carolina Panthers, San Francisco 49ers, New York Giants, Tennessee Titans. These are some of the most common searches for fantasy football lineups in Week 3.
Using The Tool. This is a simple tool but very powerful. The first step is to enter the player names that you want to compare. In the first box, search for the first player name. In the second box, search for the second player name. Compare up to four NFL players at once, and then click the Who To Start? button to see who the recommended starts are based on weekly fantasy football matchups.
Improvements For Who Should I Start? You may have noticed that our 'Who Should I Start?' tool has gotten an overhaul. We've added lots of great features for you to give you as much information as possible to win your fantasy football matchups each week. You'll see NFL player tiles with headshots and bye weeks, stats, projections, strength of schedule, player news, and enhanced search results with data to compare with a slick new interface. We hope you enjoy!
How It Works. Each week, our RotoBaller staff puts together their weekly fantasy football rankings and projections based on their research. That information is the core data that is powering the decision-making in this tool. When you search for player names, you will only see those players who are ranked. If someone is out for the week, they will not appear in the search results.
Scoring Formats. Fantasy football managers play in various types of leagues, and this tool allows you to choose whether it's PPR scoring, Half-PPR scoring, or Standard (Non-PPR) scoring. The second thing you want to do is select the scoring format. There are three small radio buttons (small circle), so click on the scoring format you prefer. The results may vary based on the scoring format you select.
