In a very preliminary ranking, I would have these four corners ahead of Peters:
1. Jalen Collins - long arms (same wingspan as Sherman), explosive breaking on the ball, tight coverage, quick and fast.
2. Trae Waynes - average arms, attacks the ball, extremely explosive and fast. Hard to pick between Collins' length and Waynes' explosiveness.
3. Ronald Darby - shorter than Waynes or Johnson but longer arms, impressive athlete, great hips and flexibility.
4. Kevin Johnson - good coverage awareness, solid breaking on the ball, size and athleticism to cover bigger receivers. Peters has a chance to jump him with a strong finish to the combine as well as Pro Day.
I might have to bump up Charles Gains to the No. 4 spot. He has made a big statement today in the drills. Only 5'10 but longer arms than Waynes and Johnson. Plays with some fire. Would be a good replacement for Lane.
