Burnthall, 6-2, 195 pounds, was known as a headhunter his senior season at Decatur. He recorded 63 tackles, three interceptions and 13 pass break ups.
Burnthall committed to Alabama in August. He said he scored an 18 on the ACT, but plans to retake the test.
Burnthall's first look at Alabama will be as a safety, but he could grow into a linebacker.
