As others have previously said, if they give up a 3rd to move up to 8 and take Jack, Elliot, Bosa or Buckner (or if in some dream Tunsil falls), they would have basically traded a third round pick for Alonso and Maxwell (and stayed at 8). Without considering the salary issue that goes along with taking on Maxwell, and if we are talking solely talent, I can be optimistic and believe that Maxwell and Alonso will be more productive than the third round pick. I think most on here can agree, considering our needs and accomplishing obtaining two day one starters in place of a third round pick rookie who will probably be garbage if the Dolphins draft history is any indication. It's a calculated risk based on the past success and injury concerns of the two players. If they return healthy and work in our schemes they make the defense much better, immediately.
Again, optimistic view. Not sure where I'm building up optimism from. You'd think the years of being a Dolphins fan would've beaten that out of me by now.
