Nose tackle has been a position of intrigue for the San Francisco 49ers for the past two offseasons. Ian Williams has long been considered to be the guy to anchor the defensive line but, for a number of different reasons, has not been able to make the position his own. That should change in 2015.
Williams won a position battle with Dorsey in 2013 but saw his season ended by an ankle injury sustained in the Week 2 loss to the Seattle Seahawks. The former Notre Dame player was handed the job in 2014 due to a biceps injury suffered by Dorsey.
