So, now that the season is over, we can look at the stats and say: who worked better with the starting unit: Jack or Calderon?
And the answer is: Calderon by a mile.
Calderon played 334.8 minutes with Derozan, Turkogulu, Bargnani and Bosh. In that time, the unit was outscored by 8, with an offensive rating of 114 and a defensive rating of 114.
Jack played 369.7 minutes with the same group of players. In that time the unit was outscored by 99 points, with an offensive rating of 102 and a defensive rating of 115.
Meaning that basically, the starting unit with Jack was NOT better defensively (slightly worse, actually), but it was much, much, much worse offensively. Which if anyone thinks back to some of our terrible first quarters with Jack leading the offense, should not be too surprising.
Of course, people like how Jack drives to the hoop, so I doubt that this will convince anyone, but there it is.
