Pittsburgh Steelers quarterback Ben Roethlisberger has only been sacked four times in his past four games and didn't get sacked at all last Sunday against the Washington Redskins. Pittsburgh's improved pass protection isn't the result of better blocking, according to Giants defensive lineman Justin Tuck.

"I hope we get some holding calls because they have gotten away with murder," Tuck told ESPN's Rachel Nichols. "They've done a very good job protecting Ben -- they don't hold on every play. But we've seen a whole lot of it."

Protecting Roethlisberger is a major storyline for Sunday's game between the Steelers and Giants. Roethlisberger has only been sacked 13 times in seven games this season. Of the quarterbacks who have thrown at least 200 passes, only six quarterbacks have been sacked less than Roethlisberger.

The Steelers have decreased their sacks without an increase in penalties. The seven linemen who have started for the Steelers this season have been called for holding five times, and left guard Willie Colon has accounted for four of them.
