Packers quarterback Rodgers can relate to what Eagles' Kolb is facing

"Quarterback school is great. Seven-on-seven is wonderful. Team drills are good. Preseason games are good. But until you have to go out and do it in the regular season and get up off the ground and deal with the different schemes that the other teams are throwing at you, particularly when you're young and inexperienced, that's a huge hurdle that some guys don't get over."

Rodgers said he never doubted he could play at this level, but admitted the game in Dallas was helpful in convincing both the organization and his teammates that the world wouldn't end if he replaced Favre.

"I think it was good for my teammates to see that," he said. "You can only convince them so much in practice. I think the organization probably got a little less worried about their long-term investment in me after that as well. But it was good for my confidence as well to go in there and play the way I felt I was capable of playing."

Rodgers thinks Kolb's play last year in his two starts has given him with same confidence boost going into this season that the game against the Cowboys gave him.

"The process [of becoming a successful quarterback] is you've got to become an expert in your offense first, then you've got to start trying to figure out defenses," he said. "It takes a while to understand what you're trying to do. Once you do, it's all about reacting to what you see out there. The quicker your reactions are, the faster you'll play and the better you'll play.

"I'm excited for Kevin and his opportunity. I think he'll do well. I just hope he waits a week."
