If anyone knows how Tom Brady is feeling while getting ready to join a new team at 42-years-old ... it's Brett Favre!
Of course, Brett left the Green Bay Packers after 16 seasons ... and spent time with the NY Jets and Minnesota Vikings before finally hanging it up after the 2010 season at 41-years-old.
So, with TB12 getting ready to join the Bucs, we dug up this clip from January of Brett talking about what it was like to QB for a brand new team on the tail end of his career ... and it's pretty great!
