Brandon Harris, CB, Miami.
The Baltimore Ravens are in need of a cornberback with Dominque Foxworth coming off a knee injury and three corners headed to free agency. Harris is the last of the cornerbacks with first-round grades to still be on the board, which makes Harris a natural target for the Ravens here. The fact that he is from MIami, and Baltimore has had success with Miami guys named Ray Lewis and Ed Reed, doesn't hurt.
The Ravens are still good defensively, but not the dominant team they were when Lewis was in his prime. An infusion of youth in the secondary can't hurt. Besides, one of my beliefs is that you need top-notch cover corners to succeed in the modern NFL, and you generally only get those guys in the first two rounds.
Here is part of Draft Countdown's summary of Harris:
A bit smaller than you'd ideally prefer but possesses just about everything else that you look for --- Extremely talented player with pure cover skills who profiles as a starter at the next level.
If the Ravens go elsewhere a name to watch might be Temple's Muhammad Wilkerson, who could fit at a defensive end spot in their 3-4.
