4. What’s with all of the third-down conversions against this defense?

Von Miller Cam Newton BroncosThe vaunted Orange Crush is still one of the most dangerous defensive units in the NFL, but what’s up with opponents putting together those long drives, and converting third downs again and again?

Through the first three games of 2016, the Denver Broncos defense is allowing opponents to convert 48.8 percent of their third down conversions, ranking them 30th in the NFL.

Now to be fair, the Broncos have faced three of the top quarterbacks in the NFL in Cam Newton, Andrew Luck and Andy Dalton. And all three of those quarterbacks are very capable of using their legs to pick up first downs, too, which they did

So, is this poor conversion percentage the result of playing some very dangerous quarterbacks? Or should we be concerned?
