A loss to the Bengals will not only fuel the QB controversy it will also raise huge question marks about the front offices ability to successfully rebuild the Broncos. Unless the plan from the beginning was to "suck for Luck."
The front office had to clear goals of improvement this season. One—the ability to stop the run on defense and two—to establish a running game that defenses would have to respect. The game against the Raiders made it clear those two goals are far and away from being realized.
The Broncos have been severely hampered by injuries in their run defense, and with injuries to both Dumerville and Bailey, the defense is now also with out its two best players.
The injury to Moreno won't have the same significant impact on the offense as the injuries will have on the defense. But there will have to be some serious praying going on for Brandon Lloyds hamstring to hold up, because Lloyd will have to be the key to beating the Bengals.
