Week 1 was full of injuries (and a lot of them entering the week, even). We also saw depth chart surprises in the opening weekend that point to some priority waiver wire additions.
Here are some of the best additions you can make to your squads based on everything we know so far. (I'll stick to players rostered on 60% of Yahoo teams or fewer and also list some other viable pickups who may be available in shallower leagues or relevant only in deeper leagues).
Quarterbacks
Jameis Winston, New Orleans Saints
Roster Percentage: 43%
Jameis Winston's five-touchdown performance didn't lead to the biggest sample size, but we can extrapolate.
