The hedge matters. That's why hedges exist is to protect the value of a bigger asset against an unlikely event that may cause it to lose value. You are a GM trading for that pick and then it hits top 4 you feel real dumb... you don't think a GM acquiring that is going to think about that? Also the hedge would figure into the expected value.
You are going to feel dumb trading for any protected pick if it doesn’t convey. The Jazz traded for a pick knowing it may not convey (or it will be converted in this case). The chances a pick does not convey is reflected in the value in that pick.
It does not matter if you own 5-30, chances at top 4 are exactly the same.
