Nike may own the rights as the official uniform maker of the NFL. But its biggest star, Tom Brady, is on Team Under Armour.

During his off (bye) week, Brady helped open the new Under Armour store in Boston. Giving Brady and UA a promotional hand was another superstar taking some time off, Jordan Spieth.

The young golf star joined Brady, Gisele Bundchen, and UA CEO in Beantown.

The Dallas native said when he’s not rooting for the Cowboys, he’s a big Patriots fan.
