Well, just to see if your thesis was true, I played my allskills well-rounded backup SF at C and my allskills well-rounded starting SF at PF last night. Here's what happened:
CenterMy guy 41k salary
C J. Castañé 43 8 - 14 2 - 3 2 - 2 4 18 4 1 2 0 0 20 10.5
His guy 60k salary
C G. Dukats 33 0 - 1 0 - 0 0 - 0 2 18 1 3 0 0 6 0 10.5
Power forwardMy guy 59k salary
PF J. Toquchar 41 5 - 15 2 - 5 3 - 4 0 9 2 0 2 1 0 15 10.5
His guy 84k salary
PF L. Daowen 41 6 - 15 3 - 4 3 - 4 2 17 4 3 0 0 5 18 10.0
Here is the game:
(26716858)Take from it what you will. To me there is no question that both of my players are far better players than his two and I would expect them to hold their own out of position thanks to their complete games. In the Center's case, he not only held his own but completely outplayed his opponent.
Once I scored a basket that still makes me laugh.
