For some perspective, when the Falcons traded up to draft Julio Jones, here's what the trade entailed:
Browns trade:
- Their first round pick, #6 to the Falcons.
Falcons trade:
- Their first round pick, #27 overall
- Their second round pick, #59 overall
- Their fourth round pick, #124 overall
- Their 2012 first round pick
- Their 2012 fourth round pick
That's the closest comp that anyone has to what a trade from #31 to #4 looks like.
