I have said this in other threads, but I think Perk would be pretty useless in a match up against the C's. He can't stay with Bass or KG , he would just get pulled away from the basket to contest their jumpers and they could easily blow by him . I don't see how he stay's on the floor for more than 15-20 mpg , Ibaka will be the main defender on KG .
Like "Who" said in the other thread, they should start Collison if they play the c's, but it's highly doubtful they will.
