Vanderbilt’s offseason search for defensive help led it to a familiar face from an uncomfortable moment, but the Commodores are looking well past that now. Former Iowa EDGE Brian Allen Jr., who helped sack former Vanderbilt quarterback Diego Pavia in the 2025 ReliaQuest Bowl, transferred to Vanderbilt in mid-January and is now being counted on to give the defense a boost in 2026.
What stands out to Vanderbilt defensive ends coach Adam Morris isn’t just one part of Allen Jr.’s game. It’s the fact that he brings both run support and pass-rush ability with real experience behind it.
“I think where he’s been most impactful is that he’s done both at a high level,” Vanderbilt defensive ends coach Adam Morris told Vandy On SI whether he thinks Allen Jr. will be more effective in run or pass defense. “It’s easy to say he’s going to help us rushing or he’s going to help us another way.
I really think it’s both. Like, he’s experienced.”
Allen Jr. spent the 2022 through 2025 seasons at Iowa. His first two years didn’t bring much playing time, but the last two seasons gave him a chance to show what he can do. From the 2024 and 2025 seasons combined, he posted 33 tackles and 3.5 sacks, with 20 of those tackles coming solo.
Now he arrives at Vanderbilt as a graduate student, carrying that recent production into a new setting. For Morris and the Commodores, the appeal goes beyond the numbers. They see a player who has already logged meaningful snaps in a demanding defense and can be used in a variety of ways.
“He is a guy that we're going to be able to trust in short yardage situations or base downs to be physical. I really think where he's most valuable is his ability to do both. He's just a kid that's playing a lot of snaps,” Morris said.
That kind of reliability matters in the transfer portal, especially for a program that values experience as much as Vanderbilt does. A player who has already proven himself in college football comes with less guesswork, and Allen Jr.’s time in Iowa’s rugged defense made him an especially appealing target.
“It is the fact that it is not as much of a projection as much because they've done it in college football at a high level. You know what type of player you're getting.
So he is talented, but the reality is any kid that you take out of the portal that’s played as much football as him you know exactly what you're getting. Then obviously it's our job to try to elevate his game in any way that we can,” Morris told Vandy On SI.
Morris is also new to Vanderbilt, after serving as the assistant defensive line coach for the Cleveland Browns during the 2025-26 season. So both coach and player are beginning fresh with the Commodores, and the early belief is that Allen Jr. can be more than just another addition. Vanderbilt sees him as someone who can help raise the level of the defense this fall.

Junior Sherrill Faces The Season That Could Define Vanderbilts Offense
Junior Sherrill enters 2026 with the kind of profile Vanderbilt has been waiting for from one of its pass catchers. After finishing last season as the Commodores second-leading receiver with 784 yards and seven touchdowns, he is positioned as a central part of the offense and one of the key voices around a group that will lean on him more heavily.
Sherrill has also made it clear he expects more than a bigger workload. He believes he can be an all-conference player and wants to be the kind of dynamic presence that changes how defenses have to play Vanderbilt, which gives this season a real chance to define both his rise and the shape of the offense around him.

Colorado Is Closing In On A Massive Offensive Line Win
Colorados momentum on the recruiting trail is starting to show up in the trenches, and Dewey Young is the latest name to watch. The four-star offensive lineman from Kalamazoo, Michigan is one of the more coveted big men in the 2027 class, and his decision comes on the heels of the Buffaloes already landing three-star running back Kylan Bobo.
Young has drawn plenty of attention from both Colorado and Vanderbilt, but the buzz around his recruitment has tilted toward Boulder as his announcement approaches. Recruiting analysts have pointed to the appeal of a stronger NIL package and the growing excitement around Colorado as factors in that lean, and if the Buffaloes do land him, he would immediately rank among the top headliners in their 2027 class.
