"Each day seems to bring more speculation about what the Cardinals will be willing to give up in exchange for the Eagles Kevin Kolb. ESPN's Sal Paolantonio recently said the Eagles want to get a player who contribute immediately, not a draft pick, in exchange for Kolb.

That makes sense because no team knows where it will be drafting in 2012. Will the Cardinals have the fifth overall pick again? Or the 31st? It's tough to base a trade on future value. On the flip side, player-for-player trades in the NFL don't happen oftn.

I doubt if DRC is on the block. He's been inconsistent in Arizona, and there's no question coaches' patience will run out if DRC doesn't mature and put in the necessary study time. But great cover corners -- and DRC has the potential to be great -- are hard to find.And it's not as if the Cardinals are deep at the position.

Patrick Peterson, the fifth overall pick, is unproven. Behind him the Cardinals have Greg Toler. The next two corners are Michael Adams and Trumaine McBride. Neither is under contract."
