MIAMI -- If the Miami Dolphins proved anything during this year's draft, it's that they know how to learn from previous mistakes.
This four-man class might not make the same waves other teams will experience from a full slate of picks, but it served a specific purpose -- addressing areas that nearly sank the Dolphins last season.
Drafting cornerback Cam Smith in the second round didn't fill a glaring need, especially after they traded for Jalen Ramsey in March. But the Dolphins were a Xavien Howard injury away from an emergency at cornerback, with Byron Jones and Trill Williams both missing last season, and Nik Needham missing 11 games.
