Is There Anyone In This Draft Worth Trading Up For Unless the Compensation Is Relatively Small?

Looking at percentages of players who earn a second contract that are picked after round 3 is eye opening. Less than 18% of picks 4-7 rnd, get a second contract or are still with the team. I think that rounds 1-3 are crucial and that's how Mickey looks at it. I'm coming over to the trade up idea but only if we use 4-7 round picks to do it, still don't like giving 1st and 2nd round picks away!
