Well said. Good strides have been made this year, but the pieces are not all there, yet. As for the O-line, yes the interior could certainly be upgraded. I'd like to see them keep Schwartz, as he can play Guard or Tackle. Albert can walk, with Fisher taking over LT and Stephenson being given a full-time job at RT. Allen, Asamoah, and Hudson can be upgraded most certainly.
As for another pass-rusher, keep an eye on a kid named Trent Murphy from Stanford, who might be available to the Chiefs and might be a good fit for this Defense. It's time to groom a replacement for Hali, anyway.
