We absolutely can, you just can't trade out of both the 1st & 2nd rounds in the next draftwe cant trade our 1st pick
We have 2 x 2nd rounders, so we can trade our 1st pick, especially if we take 2 x 1st rounders this year
Though even if you were right, it would be pretty easy to get a future 4th round back as part of the deal
