Jameis Winston hasn't yet played the Cardinals in his career. But he has played football at their practice facility.

The Buccaneers' quarterback, who will be at University of Phoenix Stadium Sunday, was in Tempe in March as one of the celebrity QBs for Kurt Warner's annual charity flag football event. Cardinals Carson Palmer, Larry Fitzgerald, Drew Stanton and Patrick Peterson were also QBs for their own teams.

"I can take so much from those guys, just seeing their true passion and love for the game," Winston said. "I really enjoyed Kurt Warner's event, because it was football. It was flag football. You reach so many people. You gave men the opportunity to play with guys that they never thought they would ever play with. That was just great. That really helped me out.

Winston got a chance to mingle with the other players, speaking with Palmer (pictured below) before the event got started, and interacting with veterans like Fitzgerald and Peterson. "I'm trying to learn and hopefully be like them one day," Winston said.

About Winston, Palmer told Tampa reporters "I love his game" and said he's played like a veteran already.

That day in March, Winston wanted to win the tournament -- the final came down to the teams of Warner and, coincidentally, the quarterback for the Cardinals' opponent next week, Tyrod Taylor -- and you could see it during the day-long affair. At one point during a break, when most teams were, you know, taking a break, Winston had his team on the field working on plays while coaching them up.

"I don't really discriminate," Winston said. "I don't care if I was playing against three-year-olds."
