Ronnie Hillman is a scary running back in the open field.

The Broncos ballcarrier gets even scarier with mouthpieces like this:

There's more where that came from. Hillman told the Denver Post's Troy Renck he's got "about 50" unique mouthpieces with that Jaws-like feel.

He'll keep wearing them as he strives to take a bite out of starter C.J. Anderson's workload. and with stats like he had against the Seahawks -- eight carries for 66 yards -- he's in line for more work.
