The NFL Scouting Combine starts February 20 and runs through the 26th. Throughout the combine, players have to prove their worth and answer questions about their draftable attributes.
Prospects could face a wide range of issues to solve, from an invisible girlfriend to arrest questions to work ethic questions.
They can also include physical concerns. From speed to size to agility, there are athletes that have to prove one or two little things to cement themselves as a high-round pick.
Whether it's a wide receiver who runs a 4.40 in the 40-yard dash instead of a 4.55 or a linebacker who weighs in at 235 pounds rather than a suspected 220, these small physical differences mean the difference between a first-round grade or a third-round grade.
Follow along as we explore the players with the most to prove at the NFL Scouting Combine.
