Tom Brady has said that the New England Patriots have missed chances to add to their Super Bowl count in recent seasons.
The quarterback won three championships in his first four seasons in the NFL, but has since lost two Super Bowls and two AFC Championship games.
The 35-year-old told SI.com: "We've had our chances. Twice. More than twice, actually. I still have plenty of chances to do it. What I've learned is it's really, really hard to win the Super Bowl. I didn't get that perspective early, winning three out of the first four years I played.
"What I like about this franchise is we've got a shot every year. I love the fact we were in the AFC title game last year, the Super Bowl the year before that and 14-2 the year before that.
"Can we win this year? It'll be determined by our level of commitment, the mental toughness. We'll find out before the season. How committed are we?"
The Patriots lost last season's AFC Championship game to the Baltimore Ravens, who went on to win the Super Bowl.
