Cardinals running back Chris Johnson is participating in the team's camp after signing a free agent contract. The deal has created a lot of buzz both around Arizona and in the fantasy world. It remains to be seen how he fits in the Cardinals' system. However, quarterback Carson Palmer has no doubts about how Johnson will fit in. "I've played against him a number of times, seen too many highlights against the teams I've played on," Palmer said. "I think it's a really, really good fit for him. This is the kind of scheme that he can get put in certain situations where he has a mismatch.
