I agree addressing WR and a pass rusher early on makes a lot of sense. I don't know if it makes sense to trade back into the 1st for our pass rusher. The initial rush on elite pass rushers will probably be over earlier than the position we'll be able to trade into BUT due to the pass rushing depth we will have quality options where we're picking in the 2nd.
I think you make a good point. That 12th pick may have to be the one used on that pass rusher and use the 2nd rounders to move into the 1st again for Patterson if he's still available. If Miami decides to re-sign Hartline and sign Wallace instead of Jennings, then I can see them address CB with the trade up instead. Which ever route we take I expect our two 3rd round picks to be on another WR and another CB.
