- : Sione Vaki: Listed Questionable (Ankle) (Sleeper injury feed)
Start Brock Purdy: 97 percent of the snaps and 0 percent of the targets over their last 3 games, against Sione Vaki's 24 percent of the snaps and 16 percent of the carries. No market projection is posted on either of them this week, so this is a usage call, and a lower confidence one than a call made on a projection. What follows is what each of them has done.
Should I drop Sione Vaki for Brock Purdy?
Yes, on the rest of the season. Brock Purdy projects 143 market-implied PPR points from Week 10 through Week 17 (17.9 a game over 8 games), Sione Vaki 13 (1.6 a game over 8 games).
