This is what we were hoping for all year long. That Orlando Franklin would fire out and HIT somebody and get to the 2nd level, that Manny Ramirez would punish somebody and get to the 2nd level, that there would be holes and cut-back lanes for the RBs, and that a RB would have a huge day.
This is going to be key going forward. Of course the Chiefs are a tougher defense than the Dolphins. Chiefs have the #1 pass defense in the NFL (198 yards a game). Broncos have the #2 passing offense (behind the Colts). Something is going to have to give.
Meanwhile however, the Chiefs are giving up 5.0 yards per rush attempt (& 130 yards/game). They're much worse than the Dolphins or Broncos (who are #2 in rush defense giving up 75 yards a game). Hopefully, the Broncos can continue to run the ball effectively, because that's the weakness of the Chief's defense.
