Need to drop a player, or possibly explore trades

I have been doing pretty well on the waiver wire, but now I need to drop somebody for a kicker. Best case scenario is a 2 for 1 trade for value, but not sure I can swing that. Who should I cut? I'm loving the upside of some of these guys. Having three players out is killing me right now, but I obviously can't cut bait there, as I believe all three of those guys could come in huge for me in the playoffs. I've limped my way to a 2-0 start.
