Tennessee Defensive Tackle Xavier Gilliam Earns Garner's Praise

Tennessee's defensive resurgence has received a major boost from defensive tackle Xavier Gilliam, a former Penn State player who has emerged as one of the Volunteers' most productive defenders during the opening five games of the 2026 college football season. Defensive line coach Rodney Garner praised Gilliam's performance and character ahead of Tennessee's Southeastern Conference road game against Arkansas, highlighting his rapid development since joining the program.

According to Tennessee Athletics, the Volunteers entered the Arkansas matchup leading the Football Bowl Subdivision with 23 sacks and ranking tied for fifth nationally with 42 tackles for loss. Gilliam has contributed four sacks and 8.5 tackles for loss, placing him third in the SEC in the latter category, according to 247Sports. He also recorded 17 total tackles and one forced fumble, according to All for Tennessee.

Garner, who is in his 37th season as a college football assistant and has coached defensive linemen in the SEC since 1998, has worked with numerous elite prospects. His career includes 37 NFL Draft picks and 10 All-Americans, giving his assessment of Gilliam considerable context.

After a Tennessee practice on October 6, Garner emphasized that Gilliam's value extends beyond his on-field production.

"X is doing a tremendous job. He's a joy to coach. Any time you can have a talented young man that's also of the high character that he is, that wants to receive coaching.

Even though he's been in our program only for six months, this guy is totally bought in. He is definitely going to be a tremendous VFL. Like I tell everybody, he's one of the best ones I've ever had, not just from a talent standpoint, but just from an overall character and everything that he brings to the table.

He's a joy to coach along with the entire room." Garner said, according to Tennessee Athletics.

Garner's assessment reflects Gilliam's adjustment to a new coaching environment after transferring from Penn State. The 6-foot-2, 305-pound junior joined Tennessee in January after considering Indiana and Notre Dame, choosing a program that included former Penn State coaches.

The defensive line coach also identified Gilliam's physical tools as central to his effectiveness against opposing offensive lines.

"Obviously, he has really good initial quickness, good short area quickness. He's got natural leverage. He's a very powerful guy.

I think he plays violent. He's violent with his hands. He doesn't just step to the offensive line, he's trying to go through them, create knock-back, cause havoc.

He's doing just an incredible job. I've been very pleased with his growth and how he responded from the spring. I think when I first got back, it was a little rough.

Got after him really good. I've just seen this kid just buy into it and is really trying to chase greatness every day." Garner said, according to Tennessee Athletics.

Gilliam's production has been especially notable given his limited previous experience. Before the 2026 season, he had recorded 15 career tackles, according to 247Sports. He opened the campaign with three sacks in Tennessee's Week 1 victory over Furman, added another against Texas and continued to contribute during the team's 24-14 win over Auburn, according to All for Tennessee.

His emergence has strengthened a defensive front that has generated pressure across the lineup. All for Tennessee reported that Gilliam and Mariyon Dye were tied for the team lead with four sacks, while Tyree Weathersby had recorded 3.5. Tennessee's overall sack total placed the Volunteers ahead of LSU, which had 22, in the national FBS rankings cited by the outlet.

Garner also acknowledged that Tennessee's defensive front still needs to improve its discipline despite its early success. Speaking to Tennessee Athletics, he described the season as particularly enjoyable because players had embraced coaching and were working to improve. He added that the unit needed to play more intelligently and correct mistakes involving alignment and gap responsibilities.

Gilliam's progress has also attracted attention beyond the college game. An analyst cited by 247Sports projected him as a potential first-round or early second-round selection in the 2027 NFL Draft, reflecting the attention his early-season performances have generated.

Tennessee prepared to carry its defensive momentum into its first SEC road game of the season at Arkansas in Fayetteville, with Gilliam positioned as a central contributor to the Volunteers' effort to sustain their early-season production.
