The Big Ten could puff out its chest over having two of its teams in the College Football Playoff semifinals.

The owner of Sonic Drive-In, Arby's and Buffalo Wild Wings is making another addition to its growing restaurant empire: sandwich chain Jimmy John's. Inspire said the acquisition of Jimmy John's will make it the fourth-largest US restaurant company, with more than $14 billion in annual sales across 11,200 restaurants. "Jimmy John's is a great fit for the Inspire family," said Paul Brown, Inspire's co-founder and CEO. Inspire Brands, a private equity-backed firm that also owns Rusty Taco, said the agreement was unanimously approved by the Jimmy John's board of directors, including founder and chairman Jimmy John Liautaud. Jimmy John's, which has more than 2,800 locations in 43 states, did not immediately respond to a request for comment.
