Collin Schaffer

Collin Schaffer is an Inventory Specialist from Laurel, Maryland. He made his debut in American Ninja Warrior 6 in the St. Louis qualifying round, competing as a walk-on. Despite showing promise in various YouTube clips, he failed the Bridge of Blades and did not advance to the city finals. His run was all cut, although clips of him in the walk-on line are occasionally used as B-roll to discuss walk-on competitors. This was Schaffer's only appearance on American Ninja Warrior; however, he tested the following season in Pittsburgh, defeating the Log Grip and Snake Crossing.

Schaffer has been a frequent contributor to the ninja community, having made over 10,000 posts on the Sasuke Maniac Forums under the username RiderLeangle.
