Football Outsiders has a new study out that isolates the Run Stop Rates for LBs and D-linemen over the 2010 season. The big thing to remember with this stat is that it exclusively measures the number/rate of positive plays made against the run, and makes no attempt to factor in blown plays and mistakes.Two Titans make the list, and at least one of them shouldn't be a surprise to anyone who watched this defense last year. Gerald McRath was one of the worst LBs in the league by this (admittedly limited) statistic. That fits the profile most of us have about McRath's disappointing follow-up to a promising rookie season. McRath never got close to getting his game in gear after missing the first quarter of the season due to a PED suspension. His poor performance stopping the run is not especially shocking though, as McRath has been pegged as a coverage linebacker since we drafted him. Still, with a completely new defensive staff in place, including a coordinator who has emphasized getting bigger, McRath can't afford another performance like he gave last year or he might find himself buried on the depth chart very quickly.
