Boardman, that is not true. My guess is you've not watched many if any Mavs games this season so far.
In a nutshell, the Mavs gave the Celtics "a starter for a starter" (Jameer Nelson for Rondo)....then added in the two bench players, Rae Crowder and Brandan Wright. To balance out contract money, I assume, Dallas also takes (from Boston) Dwight Powell.
We'll miss Wright; he's a fan fave (but basically was glued to the bench last season when Dallas took San Antonio to 7 games in the first round). Crowder...meh, no one will even notice he's gone (10.6 mpg / 3.6 ppg). Other than that, where's this "entire bench" thing you're referencing? The Mavs core bench is still pretty much intact.
They traded their entire bench to get him though so while they've got a great starting lineup there is no depth. Rondo is a free agent after this year.
