The NFL's new wave of quarterbacks still has a lot to prove to Ben Roethlisberger.
"People ask me all the time about these young quarterbacks," Roethlisberger said after the Pittsburgh Steelers' OTA session Thursday. "Let's wait. One year does not mean a lot in this league. Let's see what happens in two, three years.
"I'm not trying to take anything away from them. I think they did some great things last year, and they all have the potential to be great quarterbacks. But you don't want people to jump on their bandwagon so fast and put so much pressure on them to live up to those expectations. My advice to them is to keep doing what you're doing, playing as hard as you can because people will keep trying to build you up and it could get tough."
Kaepernick, in his second season, took the San Francisco 49ers to the Super Bowl after replacing Alex Smith as the starter in November. Griffin, Luck and Wilson all led their respective teams to the playoffs as rookies.
Roethlisberger, who has won two Super Bowls and is preparing for his 10th season, started 13 games for the Steelers and won a playoff game as a rookie in 2004. He won his first Super Bowl the following year.
