Any of these guys worth rostering?

[TheGunSlinger]

Have a few guys taking up space at the end of my 26man 1qb bench. I am a rebuilder, so took a shot with these players, but not seeing much out of them. Are any of them even worth keeping? Or do I drop and keep playing the waiver wire game?

Keep or Toss?
Joe Reed
Kendrick Bourne
Jeff Driskel
Freddie Swain
Dawson Knox

[Gator Sens]

I still think Bourne has some upside.

Knox is still worth a stash, IMO (no one else). But he's not a must-keep if you find another player that intrigues you.
