So, I looked at the lineup of Burke, Jefferson, Hayward, Favors and Kanter vs the Pacers.
This was the starting lineup. It was changed with 4:24 in the first Q. The score was 9-17 Utah.
With 3:51 left in the second Q, it put back on the floor and the Jazz were out scored 10-2.
Then it was on the floor to start the second half. The Jazz and Pacer were tied during this stretch, 14-14.
So, the overall scoring of that lineup was 33-33 and that lineup was always against the starting five.
So, Jefferson against the Pacer's starters: 33-33.
Burks against the Pacer's starters: 17-12 Pacers.
Jefferson, as limited/old/sucky as he is, is better than Burks with our real "core 4".
