In an earlier interview, Thomas reported, "There's no reason not to say Mississippi State is my top school."
That sentiment carried through today's announcement.
"Mississippi State has the home field advantage when it comes to recruiting in state," said Thomas. "I just like it over there a lot.
"I don't know. It just feels like home."
Thomas had been back and forth about making the call prior to the season, the drama is now over.
"I'm really happy," said a relieved Thomas. "I had been thinking about it a lot lately. I just didn't see any reason to put it off anymore.
"What better time than now?"
Throughout the process the Bulldogs were considered a favorite thanks in large part to the recruiting efforts of offensive line coach John Hevesy.
"You know I wasn't even his player yet, but he coached me like I was," said Thomas of Hevesy. "No other coach really did that to me.
"We just have a great relationship."
Thomas was able to inform Coach Hevesy and Coach Dan Mullen of his intentions to join the Bulldogs earlier today.
"I talked to Coach Mullen and Coach Hevesy, just a few minutes ago," said Thomas. "They were both really excited.
"I am glad to have this done now.
"Football season starts for us this week. We play Aberdeen this Friday, so now I can focus on all of that."
With his commitment, Jake becomes the 19th pledge towards the 2013 signing class for Mississippi State.
Thomas is the ninth Mississippi high school offensive lineman to commit to a FBS program prior to the season.
