The Titans are optimistic about Chris Johnson rebounding from a disappointing 2011 season. Johnson's holdout last summer helped contribute to a very slow start to the season. His 1,047 yards and 4.0 yards per carry were the lowest totals of his four-year career and caused many people to question the wisdom of the big deal the Titans handed Johnson. "C.J. has worked very hard," Tennessee offensive coordinator Chris Palmer said. "He is here, running hard and working hard. I'm very optimistic about how he's going to perform this (fall)."
