I get the sentiment but I'm going to disagree to this point.
Drafting solely for need is a kneejerk reaction that leads to reaches and makes you pass on better talent.
Great teams are always drafting value. They aren't panicking.
There will be Day 3 draft picks starting on good teams next year, I'd almost guarantee it. There'll be free agents that are a bargain that will perform well on a good team.
The Dolphins need to find THOSE guys. They need to coach them up. They need to practice. They need to develop a cohesive unit. They need to bring in tough guys who can play through minor injuries and won't be denied a yard when we need it, and we need to bring in a couple of backups so the whole thing doesn't fall apart when the inevitable injuries happen.
If we're draft a guy at 15 who is the consensus 35th-best player on the board, though, nothing's going to change with this team. If you have someone at 15 that you think can be special, you take him at 15. If not, trade down, give yourself a few more tickets to hit the bull's eye.
