First off, re-sign him no brainer. Second moving back to a 4-3 actually makes sense. Move Golden & Jones to DE, Gunter & Peters play DT, you can move Bucanon to WOLB, we would only need 1 ILB, pay Jones with CC money because then he doesn't need to be re-signed. You need a lot more in 3-4 than in a 4-3 and it would be easier for ARZ to fill those holes in a 4-3. May have to draft another OLB or sign one in FA.
I will bite.
If we go 4-3, then fine. You put Deone Bucanon at WILB which I in my merger opinion I hate (the guy is safety, stop this madness that is NOT working in the league of putting a safety at ILB), but I digress the Cardinals would have to put Bucannon at WILB, they would have no choice.
We have the defensive ends in Alex Okafor, and Chandler Jones. It would be suspect if Golden can make the switch to DE since he didn't play it in college, he played with Shane Ray in a 3-4, IIRC.
Defensive tackle, I like putting Peters and Gunter out there but, Peters is a better NT, so I would just release Peters, and try to get a more tradition DT pairing like Gunter, and Nkemdiche. But, this makes Ed Stinson, Josh Mauro worthless in this system, but that is no biggie because Xiaver Williams, and Olson Pierre fit the bill for depth.
The secondary would be fine.
The problem is linebackers......which is CRAZY because this is supposed to be a 3-4 defense and we lack 4 ILBers on this roster. There is NO WAY Minter could handle being an ILB in a 4-3, or even the Sam Linebacker position, but that is just because he can't play linebacker period.
So, the Cardinals would have to find at least 4 linebackers, and that is keeping Bucanon at linebacker. I would say it is safe to say that Alani Fua, and Gabe Martin could be salvaged as depth. But there would have to be a big investment in linebackers to pull this off.

That is how I would see this current roster fit into a 4-3. Just my opinion. Definitely a possibility, but risk blowing up a top 5 defense, and instituting a completely new playbook.
I am saying, if it ain't broke, don't fix it.
