UNC's Young Offensive Tackles Readying for Big Roles Posted Aug 22, 2017 Stepping into North Carolina's first team offensive tackle spots are a pair of redshirt sophomores. William Sweet and Charlie Heck (Jon's younger brother) are both listed at 6-7 and 300-pounds. At Monday's practice Sweet was at right tackle and Heck was at left. Both should see a wealth of playing time this season, regardless of Bentley Spain's availability. (Inside Carolina)
