I think people are underestimating the fact that I can drop Gasol down to C, put Mbah a Moute at PF, and put a very athletic Wes Johnson at the wing to help counter-act some of this "smallball" attack.
In my opinion countering the small ball attack is a bad idea for you. Size is your biggest advantage. Even if you go smaller at the 4 and 5 Calderon will get torched in a small ball type of game.
I think you are under-estimating how good a defensive combination Mbah a Moute and Pau Gasol will be.
The overwhelming majority of times when Jose Calderon gets beat by dribble penetration is off the pick and roll. Not in one-on-one situations. Those are actually fairly rare. The key to abusing Calderon is a weak pick and roll defense.
The above two players (Mbah a Moute + Pau) are Utah's best big man combination at defending the screen and roll. Calderon will do just fine defensively in that lineup.
---------------------------------------------
When you worry about Calderon is when you are pairing him with a poor to very poor defensive big man + especially slow and immobile defensive big men.
For example, Calderon and Bargnani is a disgraceful combination ... also, Calderon and Amare Stoudemire or Calderon and Shaq or Calderon and Okur would all be highly problematic defensive pick and roll combinations.
In Utah's case, Calderon + Yao Ming is where they are most vulnerable defensively to the pick and roll. They are also weak with Gallinari + Yao Ming (although given their other wing defenders, they should be able to hide Gallo on the lesser offensive threat or bench him altogether if they wish).
--------------------------------------------------
Unfortunately, attacking Yao Ming in the pick and roll on this team isn't as easy as with the Rockets because of Pau Gasol.
That makes it very difficult to go small against Utah (say a team shifts a PF/C like Bosh to center and a SF/PF like T.Young or undersized PF to the four) because Pau Gasol will have a major mismatch on the other end of the floor. So even though you've created a mis-match for your team you have also created another one against your team.
Plus, Pau Gasol gives them a second shot blocker at the rim which gives them further protection against dribble penetration on pick and rolls. So Yao has more protection here in Utah than he did in Houston. Also, the Jazz have long active wing defenders who could play team defense off the ball (away from point of attack) in pick and rolls to a high degree.
So while Yao is vulnerable ... turning him into an outright defensive liability like teams have done to him in the past (when Boston moved KG to center and worked him over with Pierce/KG in the pick and roll) will be quite difficult.
Not many teams have the creative perimeter player + two offensively talented bigs to force Yao to guard one (not much use if he's defending Ben Wallace in the pick and roll) + can defend both Yao and Pau in the post. Otherwise, you are just trading baskets.
