Not 100% sure this works out $$$ wise.
Boston sends Wallace + Brooks + 2nd
to
Bucks for Gooden and Ekpe Udoh
The celtics take on Goodens bad contract but its less money and one year shorter then Wallaces. Udoh has enough length to play some Center and gets playing time in his contract year
The bucks are not trying to tank. They are reported to have a deal with OJ Mayo and are working on bringing Jennings back. Couple these two with Sanders at Center and Ilyasova at PF they are a SF away from a solid starting lineup. Wallaces skill set fits perfectly with these 4. Add a bench of Henson, Moute, Brooks and Wolter (he will be a steal) and this is a solid team.
