The San Francisco 49ers need cornerbacks, and Christian Campbell is another corner with the size to play in Robert Saleh’s defensive scheme. Speed is an issue for Campbell, whose draft stock will fluctuate depending on how he runs at the 2018 NFL Combine.

Campbell only intercepted four passes in four seasons with the Nittany Lions, but he did break up 12 passes last season, and is a willing tackler.
