Running back Chris Johnson is coming off a 141-yard game against the Texans, and now he has his sights set on a Vikings defense that’s ranked seventh in the NFL against the run. The Titans haven’t solved all their run-game issues, Johnson said Thursday. “I feel like we have to be more consistent,†he said. “I don’t feel like one game has solved the problem, really. I feel like we took a big step, but we can’t say we solved all the problems. We have to be consistent and do it week after week.†Source: The Tennessean
