The dubious quality of running backs like Laurence Maroney and Correll Buckhalter is only part of the problem -- and anyone who thinks a healthy Knowshon Moreno would cure all the Broncos' ills is being hopelessly naive.
The root of the problem is Coach Josh McDaniels's decision to ditch Denver's zone-blocking scheme, which served the team well for many years. Even if the mostly revamped offensive line gels, players like Zane Beadles, Ryan Harris and Chris Kuper have shown little ability to overpower opponents, as McDaniels' current approach requires. Whether that's because they aren't being put in a position to excel or due to a talent deficit hardly matters at this point. They haven't gotten the job done week after week after week -- and because of their inability to open holes in rival defenses, every team left on the Broncos' schedule will be able to do as the Ravens did -- essentially disregard the run.
And in today's NFL, a lousy running game offers a one-way ticket to Loserville. Joe Flacco's stats weren't nearly as impressive as Kyle Orton's, but with Ray Rice regularly slashing the Broncos' D, they didn't need to be. Besides, big passing numbers aren't necessarily translating to wins this year throughout the league, as Philip Rivers' 431 yards in a loss to the friggin' Raiders demonstrates.
Point blank, yesterday's miseries are on McDaniels -- and if he doesn't swallow his pride and start tinkering with an offensive line approach that's not working in the slightest, he'll deserve a lot more blame as the season moves forward.
