I predict there will be a few honeymoon games where rondo controls the offense and it looks really good. But long-term, I'll make a wild guess that they will be worse off. Mavs had been the highest scoring and most efficient offense in the league. Rondos weaknesses will hurt them. The Mavs offense doesn't need a quarterback. Unless rondo suddenly finds the ability shoot, either the mavs will need to adapt or the experiment will fail. But I expect a few games where rondo has some flukey shooting performances, the team plays with extra post-trade energy, and it looks like a grand success.
