South Effingham coach Loren Purvis has a pretty good idea of what the Wolfpack will do. “Greenbrier is going to be more physical than Lakeside and Evans. They put it on the ground and try to beat you,” Purvis said about the Mustangs’ homecoming opponent Friday night. “After what we did last year (staying in contention for a playoff berth) is a heck of a turnaround,” Purvis said. And if beating Greenbrier means slowing down the run, South can be encouraged after limiting Effingham County’s solid rushing attack to minus-10 yards on 11 attempts in the first half two weeks ago.
