Backing off his previous commitment to Ole Miss just before his visit, Barber made his choice soon after getting home to talk things over with his family.
"He committed to Auburn tonight," his father, Ken Barber, tells Inside The Auburn Tigers. "Just overall it's definitely close to home and that's something that is important to Peyton. He really enjoys his home life and 110 miles is not bad at all. Family is something that is very big for Peyton with his mom and myself.
"From an academic standpoint Auburn just offers so much," he adds. "More important than anything else he really wants to get his degree and he just felt like Auburn is a great place to do that."
A commitment to Ole Miss since last summer, Barber's father says his son struggled with the decision, but in the end they felt like Auburn was the best place for his future.
"Peyton had a great experience with Ole Miss," Ken Barber says. "Coach (Hugh) Freeze and his staff were absolutely fantastic. The last few months have been really amazing for him. It was a bit of a difficult decision, but one of the things that Peyton wanted to make sure of is that for the next four years he wanted to be comfortable.
"As far as with Coach (Gus) Malzahn coming onboard we felt like it was the perfect fit for the type of offense he runs and how he uses his running backs," he says. "We just thought it was a good fit."
A physical runner who powered his way to 1,980 yards and 25 touchdowns this season for the Eagles while sharing time with talented junior Treyvon Paulk, Barber should be a big boost to a thin running back group for the Tigers.
"That really meant a lot," Barber's father says. "He has been truly blessed. He's a talented back with all of the skills he has. We've worked since he was five years old. He can block. He can catch. He has great vision. All of those things are put together to make an all-around back. He's a very hard worker. He's always trying to learn more.
"We just felt like Coach Malzahn's offense would definitely be a good fit. As a freshman coming in, if all goes well, he would definitely have a chance to play and contribute and hopefully take Auburn back to the national championship. That's the ultimate goal."
It was a big day for Milton High as along with Barber, longtime Auburn commitment Carl Lawson reaffirmed his decision to be a Tiger. That's something that was big for his son, according to the elder Barber, because the two have become really close during their high school career.
"Over the past couple of years not only were they teammates, but they were best friends also," Barber notes. "That really meant a lot to Peyton and it helped him confirm that Auburn was where he wanted to be. Nothing against Ole Miss because it was great, but Carl really helped to seal the deal."
