Sigler made the announcement at his high school one week before national signing day. He said he narrowed his choices to Auburn, Mississippi State and LSU before choosing the Tigers over Mississippi State.
"Every time I visit Auburn I have a real good feeling and it feels like home to me," the 6-3, 255-pounder told Inside the Auburn Tigers in explaining his decision to play for the 2010 national champions.
An outside linebacker in a 3-4 front on his high school team, Sigler is expected to put his hand on the ground as an end in college and will have Tracy Rocker as his position coach at Auburn.
"The toughest transition will be keeping my hand on the ground at all times," Sigler explained. "I did play a majority of the time at linebacker here (at B.C. Rain)."
"I like Coach Rocker a lot and all of the players told me he is a good coach to play for so that is exciting," Sigler said. "I also like Coach Chizik and Coach Roof (Ted Roof, defensive coordinator) so I feel real good about Auburn."
Sigler's primary recruiter was Curtis Luper.
"I can talk to Coach Luper all day, but at the end of the day I'm going to have to deal with Coach Rocker. Coach Rocker is a good guy, too. They're 90 percent business and about 10 percent fun."
Sigler, who took an official visit to Auburn in December, returned to the AU campus last Saturday for one more visit before finalizing his decision to make sure Auburn felt right. He notes that he had a really good time as he checked out the ceremony for Auburn's 2010 national championship team that attracted 78,000 fans to Jordan-Hare Stadium to celebrate the Tigers' 14-0 season.
Sigler is ranked as a three star prospect by Scout.com as the nation's No. 44 rated defensive end prospect.
Sigler made the announcement during the noon hour at the library at B.C. Rain High. He said that his decision came down to Auburn and Mississippi State even though he was recruited by a large number of colleges. "Those are the two colleges that I felt most comfortable at," he said.
The defensive end said he had an idea he could be heading for Auburn after attending a summer football camp there. "When I first went to Auburn there was just a feeling inside, a great feeling of joy," he said.
Sigler added that he liked how the coaches pushed him to reach his potential. "When I first went there for a football camp they were kind of already on me. When you find a coach that's 'Come on, keep it up, keep it up, you can do better,' like Coach (Eric) Scott did to me. That's what kept me at B.C. Rain. People asked me why I stayed at B.C. Rain. I was like, ‘I'm at home. I can live here.'"
Sigler noted that he talked often to Auburn's coaches during the recruiting process and most of those conversations were about "life" rather than football or athletics.
Since then he has been very interested in the Tigers and said on Wednesday he is glad that recruiting is finished. "It is a burden off my chest," he said.
Sigler, the nephew of former Alabama player and current Blount head coach Kelvin Sigler, has already begun to build friendships with several of his future teammates.
"Jonathan Evans went to Blount High School and I've got a relationship with him," Sigler noted. "I've got a relationship with a couple of other recruits like Keihl Frazier, the quarterback from Arkansas. I've established a relationship with a lot of guys. Erique Florence, and a few others."
Sigler plans on majoring in business at Auburn.
