Morgan & Morgan, self-described as the nation's largest personal injury law firm, has become one of the first U.S. law firms to make name, image and likeness partnerships with college athletes, signing deals with more than 20 students.

While it's hard to calculate any specific revenue uptick from the deals, the firm's founder said, the partnerships have been well received by college sports fans and the firm's marketing has spread out rapidly on social media through its new partners.
