The center position is evolving as teams line up in the shotgun more and more. Not long ago, it was important for a center to not be too tall so the QB could have an uninterrupted throwing lane. Now centers are taller and longer. Teams are also hoping to eliminate the need to have a center get help with especially big and powerful defensive tackles. A center that can handle these responsibilities without the help of a double team changes the dynamic of an offensive line. If a team utilizes a zone blocking scheme, they can get away with a smaller, more agile center, but in general, they are looking for bigger centers than ever. Centers need to be smart and have excellent awareness skills. Centers with multiple years starting in college against top level opponents have a big advantage as well.
