The four-minute YouTube video of him knocking one opposing defender after another to the ground is impressive.
His 3.2 grade-point average, his 26 ACT score and his eagerness to serve mankind in the medical field is impressive.
Still, the most impressive thing about Randall Seigler is his upside. This articulate behemoth was born July 3, 1994. Only 16, he should have several years of growth and development ahead of him. That made him one of the most intriguing prospects attending Tennessee coach Derek Dooley's recent camp.
Seigler, remarkably well spoken and mature for his age, was all smiles as he discussed his participation in the camp.
"It was great," he said. "You pretty much couldn't go anywhere else and get the same level of instruction."
Although he has played some defense in high school, Seigler appears best suited for offensive tackle. Not surprisingly, he says he spent most of the Vol camp working with offensive line coach Harry Hiestand.
Seigler developed considerable respect for Hiestand and Tennessee's other assistants during his stay in Knoxville, noting that "They seem to take directions well and execute well. The camp was very organized."
And the facilities ... well, they rank among the best in America.
"They're awesome," Seigler said. "They (coaches) say they're the best in college football, and I believe 'em."
Tennessee was Stop No. 2 on Seigler's summer college tour. He previously visited Middle Tennessee State University in his hometown of Murfreesboro. He plans to check out Vanderbilt, Miami, Texas and Duke in the weeks ahead. The fact academic institutions as respected as Vandy and Duke are on his favorites lists underscores the value he places on education.
"I'm looking for a great medical program," he said. "I want to go into the medical field or a biochemical program."
Before he starts healing people, however, Randall Seigler probably will spend the next five years knocking a lot more of them to the ground.
