Griffin's head coach told BuckeyeSports.com that the Buckeyes have been keeping their eyes on Griffin for most of his senior season.
"I think he's a guy who was a Division-I prospect to begin with," Wiggins told BuckeyeSports.com. "There's always been a watchful eye on him. The way thing worked out they had a scholarship to give. Ohio State is obviously a place he's spent a lot of time growing up. It was a big deal for him to get."
The Buckeyes did not offer Griffin a scholarship until right after signing day, Wiggins said. The coach is not sure if he ever took an official visit to the university, saying, "I imagine he's been there so much it doesn't even matter.
"He was a guy who they said all along could definitely walk on if that's what he chose to do. He made the decision Ohio State is where he wanted to go."
Griffin's father, Archie, was the only two-time Heisman Trophy winner in college football history while playing for the Buckeyes. He now serves as the president and CEO of the OSU Alumni Association.
"I think it's exciting for everybody," Wiggins said. "Anybody who grows up here would love to play for Ohio State and Adam has even more of a connection to the program with his father. It's a great thing for everyone. Ohio State got a great player with high character."
Wiggins said half the schools recruiting Griffin viewed him as having a future on defense, while the other half said offense.
"I think the only thing about Adam was he is a little undersized and that's something some people might point to," he said. "The game being such a spread game these days, with his quickness and versatility, he's got good hands and he's fast. He's got all the tools to be a great player."
Griffin also runs track and plays point guard for his high school. As a senior, he earned all-metro and all-district honors on the gridiron.
Listed at 5-9, 185 pounds, he is listed by the Buckeyes as a running back, defensive back and return specialist. That is in line with how Wiggins said DeSales used him.
"Adam really never left the field for us at any time," he said. "He played offense and defensive and returned kicks and punts. We think we got just about everything out of him that we could. He's very versatile."
Asked what Griffin does best on the field, Wiggins said it is the same regardless of which sport he happens to be playing.
"His best attribute is the fact that he's a winner," the coach said. "One thing I've said is it doesn't matter if you put him on the field, basketball court or track the kid is one of the best players on the field every single week no matter what sport he's playing. He's a hard worker and a winner. You've got to have enough guys like that on your team to win.
"That's what Adam is: he's a winner."
