ADCJ2KWatch: Adrian Peterson responds

Because we still have more than a week until the free-agent market officially opens, and because it appears the NFC North did not add to its list of franchise players Monday, we'll bring you an entertaining response to one of last week's posts.

As you might recall, Tennessee Titans tailback Chris Johnson said on ESPN's "NFL Live" that he would rush for more yards in 2013 than the Minnesota Vikings' Adrian Peterson. (As if he should have said something else.)

Monday, Peterson tweeted his response:

Peterson is a pretty competitive guy, and it appears he isn't amused by Johnson's suggestion. Which means we'll continue to follow this story for a while. Dare I say ADCJ2KWatch?
