NBA has changed to the point that an point guard like Rondo who can't shoot is going to struggle...
He is in a very bad spot in dallas because he is surrounded by players ( Monta, Dirk, Parsons, Harris ) who actually prefer to create their own shot...
He would need to go to a team where the majority of players can't create their own shot, don't want to create their own shot, and he could just dominate the ball and get people open looks...
He could put up numbers like he used to in boston if that was the case...
Nothing has really changed in his game...still has quick feet, still can handle the rock well (all the turnovers he is getting in dallas is a product of playing with does who just don't know how to establish position for a pass outside of Dirk )
Off top of my head only teams I can think of that would benefit from a player like him are Orlando, Phoenix, MAYBE Sacremento...
Him in Sacremento makes a lot of since because he would find all types of ways to get Cousins the ball...
A max...nah not seeing it, his skill is a relic of an NBA that doesn't exist anymore
