Well, it sounds like Darby already has the basics, "good feel, and use of hands" which Leodis lacks.

2) CB Ronald Darby, Florida St. 5-11, 193, 4.38 - Has world class speed and is solid in coverage. Not a big playmaker with just 2 interceptions in college. Good in the back pedal. Not physical enough in run support. Has room to grow but must improve his run support. Great timing with good recognition and gets a good jump on the ball. Good feel and use of hands as he is technically sound. Good weight distribution, slightly shorter than you would like.
