It's more important that we have someone that can guard a stretch 4, rather than have one ourselves at this time. Giles, from what we've heard, and Bagley should be able to hang due to their athleticism.
As far as spreading the floor for the Kings, it's done with Joergers offense to a degree. I know a lot of folks hate it, but the reason he has the PF trailing the PG is to keep the floor open and for the PG to be able to probe the defense before both big men get down there to setup in the post. If you have either a good passing big man, a good shooter, or one that can take his man off the dribble, then Fox can leave it for the trailer and the offense gets initiated with the PF out of the key and the floor spaced. Now, once you get deeper into the shot clock, you fall into a traditional set and score wherever the opportunity lies. Either inside or out. It's not Houston or GSW, but it's how he's doing it.
P.S. I neither condem nor condone Joerger's offense.
