Arizona Cardinals reportedly 'making a run' at Adrian Peterson, or are they?

It has been rumored for some time now, but we have another report about the Arizona Cardinals and running back Adrian Peterson. Yahoo! Sports' Rand Getlin reported a source indicated that when the Cardinals released veteran defensive lineman Darnell Dockett, they were clearing salary cap space to "make a run" at Minnesota's running back.

Peterson reportedly is willing to restructure his contract if traded to Arizona (one of a handful of teams for whom he would do so).

The Cardinals keep coming up with big-name running backs. There is Peterson, there is DeMarco Murray. There is C.J. Spiller. They also had the second-to-last rushing offense in 2014.

Steve Keim reportedly made a strong case on draft night in 2007 when the Cardinals drafted Levi Brown and that further forwards the speculation.

At the same time, there are those who just don't see how this is possible, considering the plan Keim wants to follow. He wants to have sustained success. Unless the team can get Peterson's contract to something more manageable, it would hurt the Cardinals long term.

However, there have been a number of things to happen to suggest the Cardinals are going all in for a championship in 2015.

Getlin also heard the team decline any interest in Peterson, but there is interest on the other end. The Cardinals would reportedly be his top destination to land.

So which is it? Is it the team who is interested, or is it Peterson's party who is pushing this information? How much of these rumors are real and how many are unfounded? We know that where there is smoke, there is fire (Kevin Kolb deal and others), but is this more a pipe dream or something we could see in the next few days?
