SMU Football adds transfer portal addition to improve defensive line

When it comes to building a defense that can dominate in the trenches, few things excite a fan base like adding a 300-pound force to the front line. SMU football did just that with the addition of Louisville transfer William Spencer, a powerful and promising talent ready to make an immediate impact.

1. SEC-Sized Frame with Versatility

Standing at 6’5” and weighing 305 pounds, Spencer brings rare size and physicality to SMU’s defensive interior. Originally recruited to play offensive line, he transitioned to defense at Louisville — a move that speaks to his agility and football IQ. That versatility gives SMU defensive coordinator Scott Symons a valuable chess piece. Spencer’s ability to anchor the interior could be key in disrupting American Athletic Conference offenses.

2. Power Five Pedigree and Room to Grow

Spencer joins the Mustangs as a redshirt freshman, meaning he has up to four years of eligibility left. While his stat line at Louisville — four tackles in games against Georgia Tech, SMU, and Kentucky — may appear modest, his role was far from insignificant. Louisville coaches praised his physical presence and upside. At SMU, Spencer has the potential to fill a Tank Booker-type role — not flashy, but vital. Booker helped elevate SMU’s defense in 2023 by absorbing double teams and freeing up linebackers to make plays.

3. Recruiting Win and Culture Fit

This isn’t just a roster move — it’s a recruiting statement. SMU successfully pulled Spencer away from ACC competition, including his hometown Louisville program. Out of high school, Spencer held offers from Kentucky, Virginia Tech, and Michigan State. His decision to come to Dallas signals trust in SMU’s staff and belief in the program’s vision. It’s a cultural win as much as a strategic one.

The Bottom Line:

William Spencer’s arrival adds size, depth, and developmental upside to an already ambitious SMU defense. With the Mustangs gearing up for their first ACC season, adding a player with Power Five experience — and a body built for war in the trenches — could prove to be a difference-maker.

Keep your eyes on Spencer. He’s not just a depth piece — he might be the one who unlocks SMU’s next level.
