Mac Jones is following in Tom Brady's footsteps in more ways than one ... 'cause the New England Patriots quarterback just filed to trademark his own version of TB12's nickname -- MJ10.
Records show Jones' "Mac 10 Enterprises" officially filed for the phrase on November 26 ... with the intent to use it for all things clothes -- from beanies to hats to pants to athletic jackets/shorts/shirts/sweaters and more, as reported by Darren Rovell.
We get it -- Brady didn't have the most original nickname to begin with, but the similarity is hard to ignore when the guy who held Mac's job for 20 years built a whole brand around his initials and number.
