He said one of the chief reasons was because of the school's degree program in special education, the field he wants to enter after college.
Another was Georgetown's history of success in the NAIA playoffs. The Tigers have won two national titles and finished second twice in the last eight years.
"That was a big plus knowing that every year they're competing for a national championship," Edwards said.
Edwards said it may have been a plus for him that he played almost exclusively on defense last season after Mercer merged with Harrodsburg, where he played quarterback and defensive back.
"One of the big things was being moved from offense to defense," he said.
Edwards lost a competition to be the starting quarterback at Mercer, but he said all of the schools that recruited him wanted him for defense.
Mercer coach Marty Jaggers said Edwards' attitude also made him an attractive recruit.
"He's got a great attitude, and he was one of the best leaders on our team," Jaggers said. "I only got to coach him one year, but he's a great kid. I wish I'd got to coach him all four years."
Edwards had five interceptions last season, and he tied for the team lead in tackles in the Class AA championship with six solo tackles and three assists as Mercer defeated Russell 15-12.
He said he wants to add size and strength to play at the collegiate level. He said he and Walke plan to work out this summer with Mercer trainer Todd Davis.
Edwards and Walker might not be the only Titans going to Georgetown. Edwards said the Tigers are continuing to recruit linebacker Chris Lewis and running back/cornerback Cory Jackson.
He said his visit to Georgetown last week and a meeting with coach Bill Cronin effectively sealed his decision.
He said he looks forward to joining an impressive recruiting class that includes Walker, Trinity quarterback Nick Petrino and Franklin County quarterback Kaelin Ammons.
Jaggers said Edwards will fit right in with that group.
"He's only 17 years old, and his best football's ahead of him," Jaggers said.
