He pulled the trigger April 8, saying he was impressed by how much fun and learning appeared to be going on at the spring practice session he attended.
"It just seemed like they all wanted to be out there and there was a unity to the team," he told BSB.
The premed hopeful also visited the medical center while in town.
Truth be told, not much selling needed to be done on Krenzel, who was an OSU lean before his visit.
"I had been thinking about it for a month now," he said. "I had been real interested. I wanted to wait until it was 100 percent in my mind that's where I wanted to be. I was weighing out the pros and the cons and there really weren't any cons.
"That's when I knew you can't go wrong with a place like that."
As a junior, the 6-4 1/2, 205-pounder completed 114 of 220 passes (51.8 percent) for 1,350 yards, 10 touchdowns and five interceptions.
His head coach for that season, Terry Copacia, told BSB what kind of player the Buckeyes could expect.
"Mechanically and fundamentally, he is sound," Terry Copacia said. "He's not going to throw it through a wall, but he has great touch and great accuracy.
"The thing that is unique about him is he has great instincts. When I first saw him as a freshman, he was a gangly, 6-2 kid. A couple of years later he has developed quite a bit, but he is still only 16 years old. I don't think he has even come close to what he is capable of. By the time he is 21 years old, I expect he will be quite an athlete."
"In terms of football, it was the tradition," Krenzel said. "When I was down there, they took me into the weight room and I looked in there and Eddie George was in there lifting. So were Joey Galloway, Shawn Spring and Chris Spielman. Every one of those guys who made it to the next level comes back. That says a lot for a program when you get guys like that to come back."
He said Michigan showed some interest initially but cooled after signing Brighton, Mich., standout Drew Henson in February 1998.
"It would be interesting to see those two hook up in the OSU-Michigan rivalry in a few years," Copacia said.
Krenzel became the fourth member of the recruiting class and the first from outside of Ohio. He joined tailback Kelton Lindsay of Lebanon, defensive back Curtis Crosby of Columbus Eastmoor and defensive back Mike Doss of Canton McKinley.
In terms of the 1999 OSU quarterback depth chart, he anticipated joining Austin Moherman and David Priestly, both of whom took redshirts as freshmen in 1997, and '98 signee Steve Bellisari of Boca Raton, Fla.
