He’s been the football coach at Summerville High School for 61 years, but for one day this week John McKissick turned teacher as he approached another milestone. McKissick is two victories away from 600 career wins.

His subject on Wednesday was Math 101.

“The players were talking about 600,” McKissick said. “Right now, we’re trying to get to 599. We’re at 598 and I told them 599 comes before 600. You can’t get to 600 until you reach 599.”

The Green Wave plays a Colleton County team that is 0-8 and in the midst of a 31-game losing streak at 7:30 p.m. today at McKissick Field. The Cougars haven’t won a game since Oct. 30, 2009, when they beat West Ashley, 30-27.

Chris Collins is in his first year as coach at Colleton County. He played for McKissick at Summerville and was an assistant at Berkeley and Timberland.

“Chris Collins and his staff have done a good job,” McKissick said. “He’s got a new offense. When you put in an option, you are going to make mistakes and turn the ball over. They were leading Cane Bay 21-0 before they lost, and Cane Bay beat us in the first game of the season. When you watch Colleton County play, if you don’t look at the scoreboard, they are not as bad as their record indicates.”

Summerville is 4-4, including 2-0 in Region 8-AAAA. The Green Wave has won two straight games and talk of McKissick’s third losing season in 61 years, has dissipated.

The team’s offense is becoming more consistent despite the loss of standout running back Davon Anderson, who will miss his third straight game because of a knee injury. He had 688 yards and six touchdowns before being sidelined.

Freshman quarterback Sawyer Bridges has matured each game, and Jerod Tucker has been more than adequate as Anderson’s replacement.

Bridges has completed 53 percent of his passes for 1,000 yards and six touchdowns. Kendall Parker and Sean Smith are his favorite targets with 21 and 16 catches, respectively.

Tucker has 100 carries for 581 and seven touchdowns. He also has 12 catches for 188 yards and another score.

“Jerod Tucker is the real deal,” McKissick said. “He blocks, catches and runs the football. Bridges has made a lot of progress. He was on the B-Team last year. I know we had some problems early in the year, but it wasn’t his fault.”

Should the Green Wave should win tonight, McKissick would have a chance to pick up No. 600 at Ashley Ridge next week.

Kenny Walker is the Swamp Foxes head coach and coached at Summerville before going to Ashley Ridge five years ago.

The Green Wave concludes the regular season with a trip to Bluffton on Nov. 2. The Bobcats enter this weekend’s action with an 8-0 record and are ranked No. 6 in the state.
