Tom Brady acknowledged Thursday that he's still learning the nuances of the Tampa Bay Buccaneers' offense and his role as quarterback in it.

"I think there's naturally a way that, your body just does things a certain way that it's done for a long time, without you having to think, and a lot of being a great athlete is not thinking, so the more you're thinking, it's actually slower than if you were just reacting and anticipating," Brady said. "So we're working through that. It's my first game, my first chance to play so, we'll see where we're at. We've got a big test and... there's no room for error. It's a big challenge to start the year."

The Buccaneers will face the New Orleans Saints in Week 1. Brady has faced New Orleans five times in his career, going 4-1.

"It's a big challenge because there's no margin of error when you play a great football team," Brady said. "The Saints have proven themselves to be that for a long time. They [have] a very good offense, a great defense, they're very well-prepared [and] they don't beat themselves."
