National signing day is quieter than usual in Norman, since much of the action took place during the new, early December signing date. 

But when four-star defensive tackle Michael Thompson’s signed with Oklahoma on Wednesday it still made a splash.

Thompson, a 6-foot-3, 291-pound prospect from Parkway North (St. Louis) High School chose the Sooners over Missouri during a mid-day press conference.

OU entered Thompson’s recruiting picture in January during the U.S. Army All-American Bowl and ultimately landed a steal, with help from current Sooner commit Ronnie Perkins, who is from St. Louis.

“Michael is a very athletic kid. Even though he’s 20-25 pounds overweight right now, he still moves real well and quite honestly, is still growing. I mean, he’s just a big boy,” Thompson’s high school coach Bob Bunton said.

The Sooners received letters of intent Wednesday morning from three-star tight end Brayden Willis and four-star linebacker DaShaun White, who had been previously committed.

OU’s class has 22 signees and is currently ranked No. 8 by 247sports, t-No. 6 by Rivals.com and No. 10 by ESPN. Final rankings will be updated later.
