I was just reading an article by Pat Kirwan that rates the best tandems of tackles in the NFL and he has the Bengals as #2 in the league. http://www.cbssports.com/nfl/story/19376713/lack-of-sacks-doesnt-lie-when-it-comes-to-five-best-tackle-tandems
He has that the Bengals tackles only gave up a sack every 75 passing plays they were on the field. I think this is an interesting way to look at how to rate an offensive line, but I think they need to find a way just to not rate on pass protection, but also run blocking too. But, I will take any praise the bengals can get from the national media.
