TRADEAt face value it seems like a joke. But Wally, Snow, and Jones are all in the final year of bad contracts next season... totaling just about $25 million between them. That it some major, major cap relief for the Mavericks when also adding Kidd's $21 million coming off after next year (I doubt they keep him past then).
I think there's no way the Mavs do it because I think they want to see how they manage with a full year of Kidd and a new coach... but to me their window has closed, and this could be the quickest way to make sure there is a new window 3-5 years down the road.
For the Cavs, it's a no brainer.
