maybe the "post a play in the forums and it loses" curse... but i'm gonna take a bite on 
CHARGERS TO TRADE PICK #5 at +280 (under draft specials on FD)

the fact that "NO" on this trade is juiced to -400 tells me that maybe there's intel that the Chargers will stay put and pick at #5. But assuming QBs go 1-2-3, and AZ takes Harrison at 4... doesn't the #5 slot become pivotal for teams wanting to come up for JJ McCarthy, or even to secure the next top WR of their liking? [even if AZ trades out and someone takes JJ at 4... then all the WRs are avail and #5 is still attractive]

Chargers are not in "win-now" mode. they have cap issues and a new head coach and need cheap talent. this draft is deep at OL and WR, so they could trade down and add more picks, and still get a top OL and/or WR early in this draft. they could "trade down" without slipping too many slots back, so they could "still get their guy" even if they vacate #5. 

either way, seems +280 is awfully juicy for a scenario that seems very possible.
