Defensive tackles are often the most difficult defensive players to grade because they don't have the statistical highlights of their brethren. Defensive ends can tally sacks, linebackers can rack up tackles and defensive backs can collect interceptions and passes defensed -- but defensive tackles by and large don't have a standard statistic or two to lean on.
