Brock Glenn Enters Transfer Portal After Two Seasons at Florida State
Florida State’s quarterback room is set for another shakeup heading into 2026. Brock Glenn, a former blue-chip recruit who started games in each of the last two seasons, has officially entered the transfer portal. The move, which Glenn announced via Instagram, signals the end of his time in Tallahassee - a stint that included a pivotal role in the Seminoles’ 2023 ACC Championship run.
Glenn’s message to Seminole Nation was heartfelt and reflective. He spoke of his time at FSU as one of the most rewarding periods of his life, thanking his coaches, teammates, and the broader FSU community.
“FSU football is a true brotherhood,” he wrote. “It is something that honestly is impossible to put in words.”
He leaves the program with gratitude, memories, and a championship ring - a reminder of the season that saw Florida State climb back to the top of the ACC.
But on the field, Glenn’s role had shifted dramatically by the end of 2025. After starting five games in 2024 - including a stretch against three straight Top-15 opponents - Glenn found himself behind not just one, but two quarterbacks on the depth chart.
Luke Kromenhoek overtook him late in the 2024 season, and by 2025, Glenn was the third-string option. When starter Tommy Castellanos missed time due to injury or in blowouts, it was true freshman Kevin Sperry who got the in-game reps.
With Castellanos denied a waiver for an additional season and reserve QB Jaylen King also transferring, Sperry now stands as the only scholarship quarterback on the roster with game experience. FSU did sign four-star Jaden O’Neal earlier this month as part of its 2026 class, but the departure of Glenn leaves the Seminoles with a thinner quarterback room than they’ve had in years.
Glenn’s on-field contributions were modest but not without moments of promise. In 2025, he appeared in four games, completing 6-of-10 passes for 69 yards and two touchdowns.
He also added 43 yards on the ground. Against East Texas A&M, he was perfect through the air - 3-for-3 for 56 yards - including a 35-yard touchdown strike to Amaree Williams.
He also connected with Landen Thomas for a short touchdown against Kent State and showed flashes of mobility with a season-long 15-yard run.
His 2024 campaign was more substantial. Glenn started five games and played in seven, throwing for 597 yards and four touchdowns while adding nearly 100 rushing yards.
He was thrown into the fire early, making his first three career starts against Top-15 teams - a rare feat in the Playoff Era. His best performance came against No.
15 Clemson, where he completed 23 passes for 228 yards and two scores, including a gutsy 10-yard scramble on 4th-and-9 that helped FSU convert one of its four fourth-down attempts that day. He also connected on a season-long 50-yard bomb to Malik Benson against North Carolina and ran for a career-best 47 yards on nine carries at Duke.
But it was in 2023 where Glenn made FSU history. As a true freshman, he became the only quarterback in at least two decades to make his first collegiate start in a Power 5 conference championship game.
Tasked with leading the Seminoles against No. 14 Louisville in the ACC title game, Glenn played a clean, composed game.
He completed eight passes for 55 yards and added nine rushes, helping FSU to a 16-6 win and a perfect 13-0 record - the program’s first conference title since 2014.
He followed that up with a start in the Orange Bowl against Georgia, where he threw for a season-high 139 yards, including a 55-yard strike that set up a field goal. Though the game didn’t go FSU’s way, Glenn’s performance showed his potential against elite competition. He also saw action in wins over Southern Miss, North Alabama, and Florida, finishing the season with 229 passing yards, two interceptions, and a rushing touchdown - all while preserving his redshirt.
Before arriving in Tallahassee, Glenn was one of the more intriguing quarterback prospects in the 2023 class. A four-star recruit out of Tennessee, he was ranked as high as the No. 13 quarterback nationally and made the Elite 11 Finals in the summer of 2022. His high school résumé was loaded: over 4,500 total yards and 68 touchdowns, including a senior season where he threw for 1,413 yards and 18 touchdowns while averaging nearly 10 yards per carry on the ground.
Now, Glenn will look for a fresh start elsewhere - likely with more opportunity to compete for playing time. Wherever he lands, he brings with him valuable experience, poise under pressure, and a championship pedigree. And for Florida State, the focus shifts to developing Sperry and integrating O’Neal into a quarterback room that’s suddenly very young - and very much in transition.
