As the Denver Broncos fine-tune the playbook to fit Tim Tebow's game, they have become increasingly reliant on the ground game.
With the approach, they're off and running.
Relying on an unconventional option-style offense led by an unorthodox quarterback, Denver has suddenly surged back into contention in the mediocre AFC West. The Broncos (4-5) have won three of their last four games with everyone pretty much knowing exactly what they are going to do -- run and run some more.
Not that it's mattered.
So unique is this read option -- similar to what Tebow ran during his days at Florida -- that teams are struggling to contain it.
