Gaze may not be the problem. I'm sure JVG has a lot to do with the current issues at the Kings, namely roster imbalance (I know, nobody else has noticed this. Aren't you glad I'm bringing it to your attention???).
The Kings can't do much to change their Aussie talent at this stage of the season. There aren't many options available. Isaac and Wookiee (I think) have both been on the Maric train for a while, and I think that would be a sensible option for an Aussie talent change.
They are pretty much stuck with Cadee, Thoseby, Newley, Blanchfield, Pineau, Garlepp and Humphries. The options really lie with their imports and Singh, or disposing of Garlepp. I think everyone agrees they should do this if they won't play him, yes?
Lisch seems obvious to be the import they should keep. It also seems obvious they need a starting PG and a rebounding 4 or 5. Blanchfield can and should play some minutes at 4, but is really a 3, with the potential to play some 2.
I'm not really taking Kendle into consideration, because I think his signing is an aberration, and he's only a replacement for Lisch, so he's actually interchangeable with Lisch for the purpose of this argument. I definitely wouldn't consider keeping him after Lisch's return, if I were Kings management.
Disposing of Leslie and Garlepp seems to be the best option, to me, if they refuse to play Garlepp. That way, they could look like this:
Import PG/Cadee/Lisch
Lisch/Cadee/Blanchfield/Thoseby
Newley/Blanchfield/Ellis
Ellis/Pineau/Blanchfield
Import C (or Maric)/Humphries/Singh
I'm not arguing so much about who should start in some of those positions, more that this represents a better depth chart than what they currently throw on the floor.
This allows them to continue to develop the young talents of Thoseby, Pineau and Humphries, and to see if Singh can produce anything at this level.
Give them a lineup like that, then give Gaze the rest of the season to see if he can get something out of them. If he can't, show him the door.
This is nothing against either Leslie or Garlepp. I've never really liked Garlepp all that much, but I do think the way he's been treated this year is abominable, and the Kings should just cut him. Leslie is a very capable player, just not what the Kings need.
