5. Chase Harrell
Harrell was one of the 49ers’ undrafted free agent signings. He spent time at Kansas and Arkansas, and hauled in 37 receptions for 396 yards and six touchdowns in four college seasons. He had a nice Pro Day and has some upside as an athlete, but a good training camp probably means a practice squad spot. He’d have to be truly exceptional to earn a job on the 53-man.
