Warren had a coming out party at the April 2018 Clash of the Titans Showcase at Highland Springs. As an 8th grader, he more than held his own against high school juniors, winning one-on-ones and impressing all with his combination of size, strength and speed. Line coach John Harris of North Stafford compared him directly to a young Derrick Nnadi. Nnadi played for Ocean Lakes, Florida State and now the KC Chiefs. Warren appears to be that good.
