'Nickell Robey quietly had a productive spring and seems energized by the scheme change on defense. By nature, Robey is an aggressive defender who is at his best when taking chances in coverage and blitzing from the slot. Rex Ryan's defense will allow him to do that, and he created some issues for the offense during minicamp with his blitzing. If this keeps up, 2015 could be a big year for the third-year cornerback.'
