Trading out of the first round, good or bad?

I am hoping for one of two scenarios come draft day:
1. Swap 1st round draft pick (15th) for a lower 1st round draft pick (21st to 32nd) and also add a 2nd round pick.
2. Swap 1st round draft pick for a 2nd and 7th round pick.

Either way, we would be swapping one pick for two. If not, stay pack and hope for the best.

GEAUX SAINTS!!!

Am I reading #2 wrong? How is the #15th overall pick worth a 2nd and a 7th?
