Defensive end Thomas Booker has officially declared for the NFL Draft.

The Stanford senior made his decision public via Twitter on Wednesday. He’ll graduate soon and therefore intends to forego his final year of eligibility and move on to the next level.

Here’s what Booker wrote on Twitter:

“Since I was in middle school, my goal was to play college football and come to Stanford. To say that I’ve been able to accomplish those two things is amazing.

“The connections I’ve made along the way have been just as fulfilling. The relationships that I’ve been fortunate enough to build with teammates, coaches, and staff are lasting bonds that have given me so much strength, support, and joy. Specifically, thank you to Coach Shaw, Coach Anderson, Coach Reynolds, and the entire team for believing and putting me in positions to succeed as a player, student, and most of all, as a person. The last four years have been a wild ride, and it has been those relationships and my family, that have stayed constant through it all. For that, I am forever grateful.

“I still have another dream to chase; a dream I’ve had since I was young enough to watch TV. That dream is playing on Sundays in the National Football League. With that being said, I am declaring for the 2022 NFL Draft. It’s been an honor to serve as a two-time captain while representing the best university in the world.”

The Maryland native has tremendous size as an end, and earned second-team all-conference selections by league coaches in both 2020 and 2021. The 6-foot-4, 300-pounder totaled 159 tackles, 20.5 tackles for a loss, 9.5 sacks, and an interception during his Stanford career. Booker started every game over the 2020 and 2021 seasons; he also started nine games over his first two years on The Farm. He played right away and made appearances in every game while a member of the Cardinal.
