Rivers was a productive, 45-game starter over his four seasons at Duke. He competed hard when lined up outside but figures to scoot inside in the NFL due to his lack of size and length. He’s capable in zone or man coverages, utilizing good anticipation and short-area quickness, but he could struggle to contest big slot matchups. He’s willing in run support but might be too small to finish tackles at a pro rate. Rivers is football smart and rarely stacks mistakes. He should appeal to teams looking for a nickelback on Day 3.
