Things are looking a little dicey at the center of the Commanders’ offensive line. As the Commanders make their way through the second week of training camp, the centers have drawn a fair amount of attention. Despite the absence of starter Nick Allegretti due to a calf strain, Quinn said the offensive line has held up. Last season, the offensive line was just about average in ESPN’s pass- and run-block metrics, and that was before starting center Tyler Biadasz was released in February. After practice they often put in extra work with assistant offensive line coach Shane Toub.
