Who should I cut?

I want EJ Manuel as a backup to Kaep in a 14-teamer, my cut options are:

Andre Brown
Moreno
Leveon Bell
Randle

I have TRich and CJ as starters with Tate as a 3rd if needed so in fairly set at RB. Leaning toward Moreno since I expect Denver to be RBBC all year and I already have Hicks and Cruz at receiver (James Jones is a third) so I like the insurance in the Giants passing game.

Wait a week? Or pick him up now at no bid coast?

Thanks for your help.
