I know Jerry Reese is a firm believer in this
When evaluating the cornerback position, it’s important for prospects to have good straight-line speed. But there have been plenty of NFL corners who have been successful despite lacking elite speed. Cornerback is all about body control, footwork, balance and flexibility, which in turn allows corners to more consistently close on the ball out of their breaks. It bothers me that there’s so much stock put into the 40-yard dash for cornerbacks since it’s rare that NFL corners are asked to cover receivers in a straight line. However, one test that does a good job measuring a prospect’s ability to bend, pivot, drop his weight and play with balance is the three-cone drill.
The three-cone drill strikes me as a much better measuring stick for corners than any other drill at the Combine (even the 40-yard dash).
