Jahidi White isn't the problem... it's our coaches - primarily the departed one, but coach D' hasn't rectified things yet. As I've said all season, give FJ plenty of guys to use at center and he'll make a mess of it - which he promptly did as soon as we had Jahidi. Starting him the moment he got off the plane was terrible coaching. What we needed was for FJ to have to rely on Jake so he'd have no course but to play him heavy minutes and encourage him.
What D'Antoni needs to do is install Jake as the starting center, give him lots of love and make sure he has his priorities right on the floor - defend the other teams center, defend the paint, block out on rebounds, grab rebounds, make the outlet pass promptly, run the floor hard, set solid picks, keep flushing the ball with two hands every chance that presents itself and practice his free throws. Jake can do all that reasonably well now and will improve with PT as long as he stays focussed. Generally, people stay focussed better if they are certain what their job is and I don't see any reason Jake wouldn't be like everyone else.
Forget FJ's nonsense about Jake being the energy guy off the bench - we need a stable center position more than that. Besides which, we can use energy to start the game - setting a good tone at the beginning is as important as anything.
Sure, Jake isn't everything you could wish for in a center but he's the right age for this team, he's not injury prone, he works hard and seems to be coachable. If he stays focussed and keeps working on his fundamentals I think he's on odds on favorite to become a middle rank center. For the Suns, that's a big step forward! If he developes a reliable 15 foot jumper and some cunning he might make it to the upper middle ranks.
On a related note, has anyone watched Brad Miller with the Kings... the guy has really blossomed. (At least I think it's a blossoming as I didn't see him play much before he came west.) If he keeps it up he'll be easily worth what Sac is paying him. And what a fit he would have been with the Suns. What is my point - the Sacramento Kings have been no luckier than the Suns getting draft rights to dominating centers but in the last eight years or so they've traded for Miller and Vlade - both better than any center the Suns have ever had.
