Tom Brady has worn a glove on his left (non‑throwing) hand mainly for practical reasons: to improve grip in certain conditions during his playing days, and more recently for comfort and function in the broadcast booth.

On the field: playing days

When Brady was still playing, he sometimes wore a glove only on his non‑throwing left hand, especially in cold or dry weather.

  • He explained that in dry or cold environments (like Minnesota indoors in 2014), the glove helped create a stickier feel on the ball so exchanges and ball security were more reliable.
  • He avoided a glove on his right throwing hand unless there was an injury, because bare skin generally gives a better feel for passing mechanics.

So during his career, the left‑hand glove was mostly about grip and ball control, not fashion or superstition.

In the booth: single black glove

Recently, fans noticed Brady wearing a single black glove on his left hand while working as a TV analyst, with his right hand bare.

  • He is right‑handed, and in the booth he constantly writes notes, taps tablets, and handles mics, so keeping the right hand free makes those tasks easier.
  • The left‑hand glove likely provides warmth and comfort in a cool booth, and may simply be a habitual extension of how he used gear during his career.

There is no confirmed “secret” meaning; the most grounded explanations are practicality, comfort, and his long‑standing attention to small performance details.

What fans and forums are saying

Online discussions and forum threads have had fun speculating about the look, but most of the serious guesses converge on the same themes.

  • Practical theories: easier note‑taking with the bare right hand, better control of touchscreens, and keeping the non‑dominant hand warm.
  • Playful theories: jokes about it being a “signal,” a style choice, or a Michael Jackson‑style bit, though these are treated as humor more than real explanations.

In short, the answer to “why did Tom Brady wear a glove on his left hand” ties back to what he has always done: tweak small equipment details for grip, comfort, and function, whether on the field or in the booth.
