I don't know how the chemistry would work but, if the Mavs can't trade for Dragic, I see Rondo as a cheaper option.
I think that the Mavs can be really dangerous having 2 high IQ guys, with Rondo leading the second unit with Brunson, Kleber, Powell and WCS.
I don't know if this trade works, but I think that Rondo gives the Mavs the extra ball-handling and playmaking that they need
Add picks/players if needed
