I think one of the most telling things is this:
I still do believe that we could use some depth there, despite the improved play. I mean, JC's yards and those sack stats can't be anything but proof of improvement. I also add that one thing about an offensive line I've noticed over the years is that the longer they play together, the better they seem to be, IF you have talented players there. I think with O'Callaghan, Waters, and Albert you definitely have talent. Jury's still out for me on Wade Smith and Rudy Niswanger.Chiefs quarterbacks were sacked 37 times in the first 10 games, but Cassel went down only eight times in the final six. In Denver, he wasn’t sacked for the first time all season.
But taking a look at how the offense, and how the line, improved into the second half of the season, I'd be much happier seeing the team bolster their swiss cheese pass coverage(Berry), and to get a sack-meister.
