I would take a look at these centers for the vet minimum or cheap money to help hold the fort until Perk comes back and with Wallace's uncertain status.
Jason Collins, Theo Ratliff, Brian Skinner, Tony Battie, Earn Barron, Johan Petro, those type of guys that way you can still use the full MLE however you want to.
If we are going to use part or all of our full MLE on a big especially if Wallace retires I would look at some of these guys.
Joe Smith, Nazr Mohammed if he opts out, Brad Miller, even Shaq, Brendan Haywood, Ben Wallace, Jermaine O'Neal, Kurt Thomas, Rasho Nestervic, and Channing Frye. I don't think we will be able to pry Tyrus Thomas away.
If we could somehow split the MLE with someone like Haywood, B Miller, Shaq, or O'Neal and maybe upgrade Daniels with someone from this list.
Outlaw, McGrady if he is healthy, Mike Miller (He might have to take big paycut as he is 30 now), Kyle Korver, that would be a good start to the offseason. Daniels was a disappointment and I wouldn't mind someone who can shoot the 3 taking his place if we keep Tony as our slasher/defensive wing off the bench.
