Chris Johnson is confident of achieving big things in the 2013 season. Not only does he expect to rush for more yards than Adrian Peterson, he also believes he can make a run at Eric Dickerson's all-time single-season rushing record.

The Tennessee Titans running back, coming off a 1,243-yard season in 2012, was asked on ESPN's "NFL Live" on Wednesday if he or the Minnesota Vikings' Peterson, who threatened the all-time rushing record with his 2,097 yards, would have more rushing yards next season.

"Of course, '2K," Johnson said, referring to his nickname -- CJ2K -- which he received after rushing for 2,006 yards in 2009.

When asked how confident he felt about his answer, he said he was "very confident."
