McGinn was recruited by many schools from both Divisions I-A and I-AA. Navy, Georgia Southern, Jacksonville State and Air Force all offered the Peach State native.
McGinn, who visited Annapolis the second weekend of January, had this to say about his visit: "I was impressed, it's such a nice area. The campus is beautiful. I actually got a chance to attend one of the classes with one of the seniors, August Roitsch. It was kind of neat. The classrooms are not the typical college classrooms. The typical college class has about 70 students. There were about 20 there in that class. It's a very nice area, it's right on the bay, you get a little breeze during the summer months."
McGinn has run the 40 yard dash in 4.65 seconds, which is outstanding for a lineman. McGinn, who also lettered in track, ran the relays and the 100-meter dash for Walton. Andrew has good strength as indicated by his ability to bench press 225 pounds 17 times.
As a senior, the big lineman was selected to the 5A All-Cobb County team at guard in a county that boasted an impressive 15 5A high schools. McGinn was also selected as the Lineman of the Year for Cobb County. McGinn, who was selected team captain as a senior, helped lead Walton to a 12-2 record, #4 state ranking and a region championship.
