Had the panthers had the #5 pick in the draft, this topic would be more enticing. At the moment. I don't see any team wanted to trade into the top 10 unless they are really enamoured with a player and have a huge need. Seeing as the QB needy teams all took a QB already, this indicates that there won't be a huge jump on whatever team is left to pick a QB.
I wouldn't trade back to be honest. Pick the best T or DL and move on. Unless the Raiders or the Dolphins want to trade up and offer their first rounders...stick to #7 and pick.
