Even in a deep league guys like Julian Edelman and Quinton Patton are available. Nate Washington is serviceable and undrafted in about half the leagues I'm in. I would rather have those guys on my roster than Phillip Rivers. It never makes sense to have 3 QB's on a roster (unless draftmaster format and a specific draft strategy....none of which applies to you).
Fasano...meh...I think you can do better, but if you think you know something there, then go with it. Personally, I would look for Zach Sudfeld and Zach Ertz. There is a small chance that guys like Jordan Cameron are available, but unlikely since he turned into a sexy pick. Sudfeld has been getting picked a lot lately too, but Ertz almost never does.
Kendall Hunter isn't worth much to me. Someone might have dropped Le'veon Bell (it would be dumb, but it happens). If so grab him. Otherwise, I would scour the wire for solid backups like Bryce Brown, Joseph Randle, Danny Woodhead, Pierre Thomas, Joique Bell, Pierce, etc.
Those guys should have all been drafted, but they won't last on rosters. Pierre Thomas and Joique Bell are guys that I would keep an eye on. You don't have to grab them this week. Knowshon Moreno is another guy I would think about stashing once he gets dropped week 3.
Your running back depth is pretty bad, but you can beg, borrow, and steal your way with dudes like Thomas and Bell, if your receivers are good enough.
If you can play a TE in the flex, I would look there. It isn't too difficult to get a 10 point a week guy in PPR formats.
