2001 Tom Brady Adidas Jerseys

I had a question about the mass production of Tom Brady Jerseys in 2001.

Is it safe to say that at the beginning of the 2001 season, Tom Brady didn't have any game-authentic jerseys manufactured by Adidas? Once Tom became the starter and his popularity grew, would the pro shop or Adidas have to convert other players jerseys to Tom Brady ones?

I wonder because if someone wanted a Tom Brady jersey late in the 2001 season, and was willing to dish out $250+ at the time for a game-authentic (now Nike Elite) jersey, the pro shop probably didn't have any. They most likely scrambled to customize some on the spot or Adidas was smart enough to mass produce them from recycled jerseys like linemen or less popular players.

Just wondering because I came across one of these jerseys mentioned above and I can't tell if they were even made in a season where Brady started as a back up to Bledsoe who signed a mega contract extension. I was hoping you would have any insight into whether or not Adidas or the Patriot's pro shop were smart enough to capitalize on a rare opportunity to make money on jerseys that otherwise wouldn't sell since Reebok was going to manufacture the entire NFL jersey line the following year.

Thanks!
