Keeper league - help me out sbr who should i keep?!

[imadegen]

Drew Brees
Demaryius Thomas
Matt Forte
Jeremy Langford
Antonio Brown
Cj Anderson

I'm leaning Demaryius thomas, Antonio Brown and CJ anderson although I think Demaryius Thomas production will go down without peyton manning. Forte production will slow on jets. Langford looking real solid preseason though. Thoughts?

What do you have to give up to keep each player? That is the most important question.

How long do you get to keep these guys? If it's forever (and no cost per round), then I'd rank them like this:

Brown
DT. (May be a down year, but hopefully will be solid for a long time)
Brees/CJ Anderson (coin flip)
Langford (go with the younger guy)
Forte
