I have to think Carolina would be interested. Their first 2 picks (9 and 41), plus their 4th round pick, plus next year's 1st round pick would be enough points.
They have 3 picks from San Fran, so even by trading us their 2nd and 4th, they would have SF's 2nd and 4th this year.
Not sure we want to trade down that far though. I don't know that Indy would be willing to pay the price. They don't have a lot of picks and they'd have to trade #4, #35 and next year's #1 to get there.
