The lack of Woodhead may have an impact on Royal's consistency here. At the least, I think it bumps him up in the red zone passing priority list. (ie: 1. Gates, 2. Allen, 3/4. Royal/Floyd?). Donald Brown isn't nearly as much of a threat as a receiver as Woodhead was. Branden Oliver may be someday but he isn't there yet. Perhaps they go run heavy again when Mathews is back. But they've seen him go down again and again now, so I doubt they risk leaning on him for much more than a game here or there. Plus their offensive line is struggling to run block. It should improve with Mathews but not by all that much. They are going to pass plenty each week.
Through Chargers' first 4 games:
2013: RBs targeted 37 times (26.4% of team targets), 32 receptions, 240 receiving yards, 3 TDs, 15 first downs
2014: RBs targeted 30 times (21.9% of team targets), 25 receptions, 185 receiving yards, 0 TDs, 10 first downs
In 2013, Woodhead and Mathews had almost all of that production: 33 targets, 28 receptions, 219 receiving yards, 3 TDs, 14 first downs.
In 2014, Woodhead and Mathews had the following before getting hurt: 10 targets, 9 receptions, 80 yards, and 7 first downs. So the rest of the RBs have combined for just 3 first downs and 0 TDs on 20 targets.
So there is reason for the Chargers to look elsewhere, at least until Mathews gets back. Through the first 4 games in 2013, Royal had 19 targets. This season he has 29. And that is with the team attempting 3 fewer passes in the first 4 games this year, so it isn't about being pass happy.
I would say Royal's production should stay up at least until Mathews returns. (Barring injury.) After that, the coaching staff should use Mathews more in the passing game... but they should have done that last season and to start this season and didn't. So it's hard to say if they will do that. Maybe Brown's performance will finally open their eyes. If so, Royal's production will likely tail off a bit.
