Great deal by the Dolphins. They're being operated really well (the Tua decision aside, which could be their downfall despite all the good stuff). I guess the 9ers see it as being late first rounders, which wouldn't make it so bad, but if they fall apart and have a bad year this season or next the Dolphins will be really nicely placed.
Even if they're late rounders they can package picks now if Tue doesn't improve and move up for a guy in the next two drafts
