Re: Time to get Offensive...
Another reason, along those same lines, was that teams knew that the Steelers would also try and throw on First down to get managable 3rd situations for Ben and the offense, so they would drop back into a zone defense and bring everybody into coverage, to keep him from getting big chunks of yardage on 1st down, then they knew we'd try and run on 2nd down to get some of that yardage back, and then it was 3rd and long, and they had him right where they wanted him.
That just comes w/ experience, knowing about reading defenses and taking what the defense gives you. That just comes w/ time, and he's had a full year and double the amount of games he used to playing in to get more adept to it. So I look for big things from him this year.
