Many undrafted rookies have a wow moment at training camp. Perhaps the player makes a specific play or strings together multiple standout practices. At times, one sequence during team drills can draw attention.
We often hear about Denver Broncos running back Phillip Lindsay's rise up the depth chart to become a Pro Bowler in 2018, but don't forget about Gus Edwards, who led the Baltimore Ravens in rushing yards (718) last year or J.C. Jackson, who carved out a decent role within a competitive New England cornerback group.
All of them went from undrafted to a consistent game-day contributor.
