I think most people in this forum are already overrating and overhyping Rubio and he hasn't played even a single game for the Jazz. It is very problematic to make use of Rubio and at the same time have a great offense because of his somewhat limited skill set. Previously, Rubio was terrible at shooting from mid-range and from outside. Recently, though, he became good from mid-range but still remains subpar from outside. Well, if that wasn't problematic in itself, he absolutally can't finish around the rim. What made Stockton and Malone P&Rs very effective was that they could take advantage of whatever the defense gave them: not only Malone could drive and finish, but could also make the mid-range jumper; not only Stockton could take the long-2 but also - and that is specially important - drive to the basket and finish it. With Gobert and Rubio's P&Rs, Gobert wouldn't be able to make the mid-range jumper (at least for now, it seems) and Rubio wouldn't be able to drive and finish it. That's a given! Moreover, Rubio might not be able to hit the long-2 with any consistency. Hence, we are talking about a very defensible P&R with Gobert and Rubio.
Realistically, what I think it can be expected from Rubio are the following: (1) willingness to pass instead of forcing shots; (2) good overall passing that not necessarily would result in assists, since the defender doesn't have to guard him thightly; (3) lots of antecipations on defense, playing the passing lanes well. That's it, IMO.
