I was reading that quote this morning .... while there is some truth to it, I really think that Tomlin was just trying to show some love to the much maligned O-line. Ben is not the only guy in the NFL to hang onto the ball a bit. Manning holds it a lot, too, but the Giants line still gives him protection and he barely gets tapped compared to Ben. Plus, some of the deeper patterns the Steelers run take forever to develop ....
The offensive line is, obviously, the Steelers true weak point. Lucky for Pittsburgh that Roethlisberger has the chops he does ... that, plus the guy can really take a beating better than almost anyone else in the league. When you can say that the O-line played well after the QB is sacked 3 times (and generally pressured or hit on the rest of the plays), that isn't the sign of good stuff to come from the offense ....
