Buchanan’s draft stock could be tied directly to his size, athleticism and upside on special teams and in coverage. With below-average play recognition, he becomes more helper than hero as a run defender. He’s twitchy in short spaces and can float through space on fluid feet and smooth hips when asked to cover. Buchanan has physical tools to work with but might never get there as a run defender. Still, if he can cover and play special teams well, he might make a team.
