"The last event was the mile," said Atchison, who was also the track coach. "You can imagine him, 218 pounds and built like that. Anything over 400 yards and he's ready to cash it in.
"He asked me, 'Coach, if I'm so far ahead nobody can catch me, do I have to run the mile?'
"I said, 'If you're that far ahead, you don't have to run, but we better wait and see. There's some pretty good guys.'
"And I mean, the guy--he ran a 9.7 100 yards. That was the max. If you ran 9.8, you got 1,000 points.
"He threw the discus over 150 feet. That was the max. He threw the shot over 50 feet. That was the max. He triple-jumped over 44 feet. That was the max. He ran the hurdles in 12.9, and I think 13 was the max.
"We didn't even have a track at our high school. We have no pits or anything, and you have to pole vault in the decathlon. We couldn't even find anyone to loan us a pole because most poles aren't made for someone who weighs 218 pounds.
"Another high school let us borrow one, a pole for a 180-pounder. Bo used that and pole vaulted 12-6--and never touched a pole until the day he walked out on the track. I really didn't know if it would hold him up or not.
"But again, after about three tries, he looked like he'd been pole vaulting all his life. Bo's the kind of guy, he can watch somebody do something and do it.
"We said a lot of crazy stuff when he was at Auburn. We really never felt like he'd turned it loose. A lot of times, it looked like he was holding back, as far as making cuts and doing little things that we'd seen him do in high school.
"I don't know if Bo has ever played to his potential. That sounds crazy, a guy who's gone to L.A. and has gotten over 200 yards rushing in a game. But he only does what he has to do.
"I can remember his senior year in high school, we went to the state track meet. The state record in the triple jump was 44 feet. Bo had jumped 44 during the season, but this was the state meet. Well, with only one jump left, a kid from Fayette goes 47-8. Everybody in the stands is going, 'Oh, that record will never be broken. That's over 3 feet longer than the old record.'
"Bo had one jump left. I'm sitting there with my assistant coaches, and he goes after this kid--and he goes 48-8. And I mean, you knew when he was sitting in the pit he had broken it. That's what I mean. Had that kid jumped 48 feet, Bo might have gone 49.
"I saw Bo his senior year in high school high jump 6-9 indoors. He still holds the indoor record. Two hundred eighteen pounds and he high jumps 6-9?
