SMU football’s secondary is standing out in spring practice, with coaches praising the corners, safeties and nickel depth as the Mustangs chase more defensive growth.
SMU football spring practice has put a bright spotlight on the Mustangs’ defense, and the secondary is quickly becoming one of the biggest storylines.
With staff changes, new leadership roles and a sharper edge in the defensive backfield, SMU looks intent on taking another step under Rhett Lashlee heading into the 2026 season.
That starts with a group that appears more confident, more physical and more competitive than it was a year ago.
The message from inside the program is clear ... SMU doesn’t want to just be good on defense again. The Mustangs want to become one of the best units in the ACC and a nationally respected group.
The cornerback room has been especially active this spring. Jayvon Thomas has brought urgency to the group, while Marcellus Barnes and Speedy Nettles have continued to build on what they showed last season.
Younger players like Javion Holliday are beginning to push for a bigger role. That competition has helped create a more aggressive style on the outside, where SMU wants its corners to consistently challenge receivers instead of simply reacting.
There’s also intrigue at nickel, where Jarvis Lee has made that spot one of the liveliest position battles of the spring. Versatility matters in a defense that asks the nickel to cover, pressure and support the run. Jaden Milliner-Jones has added even more flexibility by showing he can move around and help at multiple spots.
At safety, Tyren Polley continues to flash the instincts and range that made him a standout last season, while Jimmy Wyrick has impressed with his leadership and steady presence. Jaylen Moses is another player drawing praise after embracing a bigger challenge in the system.
Put it all together, and SMU’s defensive backfield looks deeper, tougher and more intentional this spring. That doesn’t guarantee anything in September, but it does suggest the Mustangs are building a defense with a much higher ceiling.
