There was not one, but TWO Bradys working out at QB at Buccaneers practice on Wednesday ... 'cause Tom's son got in some drills while visiting Dad -- and TB12 loved it!
15-year-old Jack swung by Tampa's day-before-Thanksgiving practice for a few hours -- and at points during the afternoon, he got to toss around the pigskin in front of Tom.
The high schooler -- who actually plays free safety and a little bit of quarterback for his H.S. team -- looked good ... rollin' out of the pocket with two hands on the ball, just like pops.
