What about Bob?

Now that the Cardinals are saying publicly that they'll listen to offers for disgruntled wide receiver Anquan Boldin, there's plenty of speculation about where he'll end up.

The Giants have long been mentioned as a potential suitor, as have the Iggles and Bears.

But when it comes to trades, teams generally prefer to trade out of the conference. After all, the last thing the Cardinals want is to deal Boldin to an NFC team and then have that team beat them either in the regular season or the playoffs.

Consider: With Boldin, the Cardinals beat the Iggles in the NFC Championship Game last season. And remember the Brett Favre trade? The Packers could have had a deal with Tampa Bay, but chose the AFC Jets instead. And Denver dealt Jay Cutler to an NFC team, bypassing the Jets, among others.

The problem for Arizona is that there aren't a lot of AFC teams lining up for receiver trades.
