If you expect Kamara to not receive a suspension this season anymore, keep him. But keep in mind there still is a chance he may not be available for the fantasy playoffs.
Saquon is an option, but don’t buy into the hype train. He’s a mid- to high-end fantasy RB2, not more.
Deebo will struggle to remain in WR1 territory, and if at all, he will be a low-end WR1. Lance will take away all his rushing volume (including the TDs). Plus, he’s showing some chemistry with Aiyuk in TC. Don’t keep Deebo.
And Pitts is a very good TE. The question is, do you want to spend a keeper slot on a TE? In redraft, Pitts is a top 6 option, but not necessarily top 3. I really like Pitts, but wouldn’t recommend to keep him.
With only two keepers, it’s not like you really have to think long term, and while it’s tempting to keep the #1-rated QB, Josh Allen is still a QB. You wouldn’t keep a defense just because it’s the #1-rated DST would you?
