Both players are ~30 and are not getting any better. This team isn't good enough to win a championship right now, it needs to improve. I think we can definitely get younger talent with more potential through FA especially with the Wall/Beal combo in the back court. I'd rather not settle for round 1 or 2 flameouts in the playoffs every year ie Atlanta Hawks

I would. As stated above both Gortat and Ariza are as good as they're going to get. We all know they're not good enough to win the championship as is and they're more than a key bench player away from doing so which in itself would be hard to do if we bring these guys back at $10 million/year.
Let's also not forget we've already resigned Martell Webster for another 4 years and just drafted Otto Porter. The money that would go to Ariza would be better spent on depth, specifically in the post.
