Holder will remain on staff as Greenbrier's offensive coordinator for the upcoming football season.
"Based on a possibility, is all it is," Holder said Thursday of his decision.
Holder said former Richmond Academy coach Chris Wilkins will be the Wolfpack's next baseball coach, pending approval by the Columbia County Board of Education. But Wilkins said he had not yet been told anything for certain.
He was on hand Thursday when Greenbrier athletic director Garrett Black gave parents and players the summer workout schedule and informed them that Holder would not be back.
"It was news to me that Rodney's stepping down," Wilkins said. "I'm just excited to be a part of the program."
Black said he had a "good idea" of the direction the search would head, and said he would like someone in place before summer workouts.
Black contacted Wilkins around the beginning of March. The Musketeers coach told his players after their 10-0 loss to the Wolfpack on March 18 he'd be leaving for Greenbrier.
Greenbrier assistant principal Penny Jackson, who will be Grovetown's first principal, will lead the search for the school's athletic director. Holder said he talked with Jackson and plans to apply.
Holder is in his second season at Greenbrier. The Wolfpack won the 2007 Class AAAA state championship under Holder and begin a run at a third consecutive title today at home against Americus-Sumter.
Holder arrived at Greenbrier in 1999, serving as an assistant baseball coach under Ed Williams from 2000-2004.
Holder said he realizes he's taking a chance with his decision.
"If it didn't work out and I had to come back and teach, that's not so bad," he said. "I've just always wanted to be a head football coach."
