The AFC South side are yet to take a win this season, and face the San Francisco 49ers in London later.
The running back told Sky Sports News: "Whenever you start 0-7 there are certain ways you can handle it.
"I think the guys have handled it well. It's a challenge to fight out of the hole that we've dug ourselves into.
"We feel like we've got the players who can do that. Certain games we have great execution, other games we don't, and that's the inconsistency that we're trying to defeat."
The 28-year-old has 316 rushing yards and two touchdowns in 2013.
