Why do we want to turn every PF into a SF?
Imagine in a couple of years we have to trade one of the bigs because we can't afford to keep all 4.
Vonleh, Kanter, Favors: Vonleh gets all his time at PF; Kanter splits time between PF and backup C.
Vonleh, Gobert, Favors: Favors and Vonleh start. Favors slides over to PF when he and Gobert are in the lineup together.
What if Gobert doesn't develop? Then the Jazz have their 3 bigs in Kanter, Favors and Vonleh. Gobert plays short minutes off the bench or isn't re-signed after his rookie contract.
