Your fantasy football team will never look as promising as it did on draft day. So much has changed after just three weeks, and managing a successful team is a constant and demanding weekly responsibility. Don't concern yourself so much with "Rest of the Season" outlooks when a roster will continue to change every week. The next matchup should be the specific focus. 

As a rule, I usually do not feature players that are rostered in more than 56% of leagues on CBSSports.com, because those guys are usually not available in many competitive leagues. This week, though, I made an exception for two running backs who should be on more free agent lists on other platforms. The analysis leans to PPR formats. 

Before you determine which players you should target on the Fantasy football waiver wire ahead of Week 4, you NEED to see what Scott Engel has to say.

Now, he's revealed the best widely available free agents following Week 2. Two key players to target on the Week 4 waiver wire: Vikings quarterback Sam Darnold and 49ers receiver Jauan Jennings. Engel has full breakdowns for both players.

Engel is also in on a key rookie running back! This player should be in for a big role that requires using 56% of your FAB budget to secure as he could be a HUGE boost to your roster moving forward! You ABSOLUTELY need to see who it is before making any Week 4 waiver wire claims.
