Or, they could trade him for picks, sign Dansby and Wilson and go after Asomugha.
If I were Graves, this offseason I'd have trade agreed upon in principal with some team for Boldin with the understanding that it's contingent upon getting Asomugha on the team. Once we get him, then the trade agreement gets signed. If we can't land him, then we work on keeping Boldin.
It's just my humble opinion, but I think the Cards would be better served with a the best CB in the league and the best WR in the league than with the two of the best WRs.
I respectfully disagree. I think with NFL rules setup as they are a WR is of greater use to the team than a corner.
Objectively I think we can agree that Boldin and Asomugha have roughly the same value for their positions.
Boldin's value to the Cardinals is also dependent on many factors. If the team keeps Warner, it dedicates itself to the wide-open passing attack we're seeing now, which means the team needs the best WR's it can get. If we pay Warner, we should pay Boldin.
If Warner decided to move on, then we'll see an offense more-akin to what Whisenhunt started with, ala Pittsburg's run-based style, in which case one electrifying WR should be plenty with a competent supporting cast.
The bigger concern is continuing to build on the pass-rush. I'd rather pay big money to a rusher than a CB, because a great pass rush makes like easier for the secondary.
The reverse is true too, but not to the value of the first.
On defense I'd pay highest in this order: DE, SLB, MLB, NT/DT, S, WLB, CB.
Not because a good CB isn't as important, but because the great ones cost too much and are hamstrung by too many NFL rules.
