NFL fans are speculating whether Tom Brady is second-guessing his choice to come out of retirement

Brady said, that he "definitely" still finds enjoyment in playing football. He's eager to watch how the club presently bounces back from its rut

"It challenges you in every area, physically, mentally and emotionally,"

"And indeed, at this stage we're in, this is where you've got to dig deep and see what you're all about

And see what kind of character you have, what you believe in, and your values as a team.

Brady has never played for a team with a losing record since sitting on the bench during his 2000 rookie season.

Yet Tampa Bay has fallen below .500 following back-to-back losses to the Pittsburgh Steelers and Carolina Panthers.
