"It's a little bit of the offensive line not doing a good job of being consistent,'' Kalil said. "We've done a really good job of pass blocking, but we just have to be better [run blocking]. We can't have a 'my bad' from one player on one play and then another guy the next play.''
"You can't let guys go that we're responsible for,'' Kalil said. "It's one thing to get beat. That's going to happen. But you can't not block a guy that you're supposed to block. That starts with me. I've got to make sure everybody is on the same page.
"But that's a big part of it. You can't let guys run free and take shots at the running back.''
Coach Ron Rivera called it a "tough day'' for the running game. He hopes the return of all-time leading rusher DeAngelo Williams helps on Sunday night against Pittsburgh.
But even with Williams the Panthers had only 54 yards through three quarters of the opener against Tampa Bay.
Jonathan Stewart led Carolina with 37 yards against the Lions. Twenty-two of those came on one run.
"And those yards were all from second effort on his part,'' Kalil said. "Imagine if we could block a little better for him how many yards he could get.''
"Jonathan, he just ran his butt off. Even on the [2-yard] touchdown, he had three guys on him. If you watch film on it, it's unbelievable. We've got to do a better job of blocking for him.''
i expect a much improved performance from the oline this sunday night against the steelers. there was definitely a lot of run for improvement the past couple of weeks, but at the same time the lions' and buccaneers' defensive lines are pretty tough to run on...the steelers, not as much.
