Moncrief, who joined the team last season as a junior, played in all 13 games last season. He started against Ole Miss and made 14 solo tackles with 13 assists. He deflected one pass and forced one fumble.
"It's a business decision," Moncrief told Inside the Auburn Tigers. "College football is a business and I just think about my future as a last-year player and my value going into my future as far as my NFL hopes."
Asked if it was a difficult decision, he said, "It was a very tough decision. You're thinking that's the school that is the best fit and everything, but God just shows you things," Moncrief said. "You just have to follow His footsteps and that's what I did. I just prayed about it. Everything is going to be all right. I feel very comfortable and confident in my decision."
With Will Muschamp taking over as defensive coordinator this year Moncrief was expected to begin preseason practice as a backup to true freshman Tim Irvin at the nickel/strongside linebacker position.
Asked if the position change factored in his decision, Moncrief said, "It was a good, versatile fit for me, but it didn't play a big role for me. It was more about just the opportunity."
Originally from Prattville High School, Moncrief played two seasons at Mississippi Gulf Coast Community College before transferring to Auburn. He said that he is looking to transfer to a program in the ACC, Big Ten or Big 12.
Kamryn Melton is show at an Auburn practice.
Melton played in three games as a true freshman in 2013 for the SEC champions, but a knee injury cut short his season. Last year the cornerback did not play and following spring practice and there was a good possibility that would have been the case again this fall.
Melton signed with the Tigers out of Dothan High School.
"I want to thank Coach Malzahn and the Auburn coaching staff for giving me an opportunity to attend and play football for such a prestigious school," Melton said in announcing his decision.
"I also want to thank the Auburn Family and fans for the life-long memories I made on the Plains," Melton added. "In my heart I will always be an Auburn man, but after praying and having a discussion with my family I have decided to transfer."
