The Panthers continue building up their defensive line after adding Auburn DT Derrick Brown with the seventh overall pick on Thursday night. Gross-Matos will only help bolster that unit. The Penn State alum is an effective pass rusher and run defender who totaled at least eight sacks in each of the past two seasons. Carolina spent the off-season solidifying their offense under new coach Matt Rhule. So far they are using the draft to strengthen the defense.
