RB2 or WR3 at flex this week?
Read your Sleeper league · Fantasy GM
Start your RB2. Over the last three games he's played 71% of snaps and handled 8 of his team's 11 carries inside the 10. That goal-line role is the most reliable path to points on your bench. Your WR3 is trending the other way: his target share dropped from 23% to 15% once their WR1 returned, and Sunday's opponent has allowed the fewest fantasy points to receivers over the past month.

Is there a trade that fixes my RB depth?
Compared all 12 rosters · Fantasy GM
Best fit: Deep Ball Dynasty. Offer your WR2 and bench RB4 for their RB1. They have two running backs on bye in Week 9 and three healthy receivers sitting on their bench, so a WR upgrade fills a hole for them. You haven't started your RB4 all season, so you're giving up almost nothing you use.
